100% CPU
Hi all, We're running a CFMX 6.1 / SQL server 2000 app on a 1.6GHz AMD server with 1.5Gb of RAM. The app gets about 2.5 million page requests a month, peaking at about 7000 page requests per hour. Since yesterday morning it's suddenly started to misbehave, with the processor regularly maxing out at 100%. It will run clean an fast for 20 minutes or so, then suddenly requests will start to queue up and the whole thing grinds to a halt. Usually it recovers, but sometimes the service needs restarting to get it back. The app is well behaved, with most requests taking about half a second. There seem to be no particular long running requests that trigger it. This happened a couple of months ago and I restricted the amount of memory SQL server used and increased the RAM on the box to 1.5Gb. It currently appears to have about 3-400Mb free. I've installed the CFMX updater (released a few days ago), reinstalled ColdFusion, scandisked the drive and defragged. I wonder if anyone can give me any clues on what else to look for. Surely we should be able to get more traffic out of this spec machine? Many thanks Ian Buzer [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings] [Donations and Support]

Re: 100% CPU
Hi vishnu, Thanks for the reply. Just to understand what this does Am I right in thinking this controls the cf scheduler? I'm fairly confident that our load problems are not related to scheduled requests as these occur overnight. Or does the scheduler have other implications?

RE: 100% CPU
Ian, We have seen this behavior as well. When we start experiencing the page slowdowns and notice the jrun CPU very high we will stop and restart the CF Application Server, this "fixes" the problem. Yes the pages are down for a few seconds but in our environment this is not as big a problem as having the slow page response, or the page never coming up at all. __ Bill Grover Manager, Information Systems Phone: 301.424.3300 x3324 EU Services, Inc.

RE: 100% CPU
Hi Ian. We have had this problem as well, on both Windows 2003 and Redhat Linux servers. There doesn't seems to be any logic cause of the problem and therefore no fix. The only way to work around the problem is to restart the server regularly. We have a scheduled task on both Windows and Linux to restart the service once a day, which seems in the most part to have fixed the problem, but it still happens from time to time.

Re: 100% CPU
Hi Andrew, Bill, We've been running ServersAlive for the last couple of years, which has been cycling the service automatically everytime the system slows and like you say, this has worked well as a backup. Trouble is, it was doing this about every 10 minutes when we had our recent problems - not really acceptable! I've been doing my sums - 7000 requests per hour is on average 2 requests per second. I guess in real life this could increase to say 4 requests per second for a few minutes at a time. Maybe this is as much as a single processor can handle? What other loads are people getting out of a single processor machine? Thanks Ian [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings] [Donations and Support]
RE: 100% CPU
Bill, I went through a similar process with a client of ours. We did several things to mitigate this issue. 1. Eliminate Access dbs. If you have anything running on Access get rid of it. 2. Make sure and use the JDBC Merant 3.3 drivers for SQL - this is an update from 6.1. 3. Check out long running db requests - maintenance tasks, utility tasks, data imports, exports and dumps ect. Create a separate datasource for these, restrict the number of connections and deselect the "maintain db connections" for that db resource in cf admin. 4. Fiddle with the JVM maxperm memory, and heap sizes. Try to get them large enough so that the heap is not being constantly resized and garbage collection is efficient. There are a ton more JVM settings depending on the JVM you are using. 5. Use Perfmon to figure out which resource is hanging. 6. Consider increasing the process isolation in IIS for the application - it can tell you if IIS is having conflicts with other processes outside the ap. 7. Check the web logs for a burst of http requests at the point of failure. One customer I know created a dynamic publishing system with constantly updated content - then he used google adsense to serve ads and make himself money. But every time a new page was published (new to google) the googlebots attack to figure out which ads to serve. Since his server was near capacity this sometimes surfaced as a denial of service type attack (much like you are seeing) - and since many of his pages were driven by database calls it looked like a possible db problem - or connection issue etc. 8. Consider moving the SQL server Off of the web server. 9. Make sure and use a FQDN for the server name in the database administrator. In other words, don't use "127.0.0.1" or any other IP address. use "sql.mydomain.com" type syntax. In fact, put the domain in the HOST file if you have a default win server configuration. Windows will check the host file first to resolve the domain - which saves a dns request. JDBC will attempt to resolve an ip into a domain name using reverse lookup before making a connection. In many cases this results in a lengthy initial connection request. Having a guaranteed resolution to a flqn (a la the host file) eliminates this problem. That's my short list - anyone else? Mark A.

RE: 100% CPU
One more I forgot We have noted that the docs say the the "simultaneous requests" number in CF admin should be roughly 2x the number of procs. While this number works well on a busy cf 5 machine. It seems to be quite low for a cfmx platform. We've increased this number to between 8 and 13 on a dual proc machine and seen significant results. On a single proc machine I would try 6 and see what you get. -Mark -Original Message- From: Andrew Dixon [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 31, 2004 8:21 AM To: CF-Talk Subject: RE: 100% CPU Hi Ian.

Re: 100% CPU
Great info Mark, Didn;t knwo the ahile don't use IP for database bit. I want to stress on he one Mark almost forgot. At the machine in question's current proc speed I'd say 6 MAX and since you figure 4 max request ever I would lower it to 5.

RE: 100% CPU
Bill, FYI In regard to point 9 below. When you use a regular "server name" instead of a FLQN name you cause the JDBC server system to do the following: First it uses the unc service... check the host file for that string to resolve (no dice) check dns (also no dice) .move to rnc service (windows locator - basically a handoff to windows) check lmhosts file (if enabled and configured to do so)... check active directory created flqn on the nearest dc if you are on a domain ([EMAIL PROTECTED]) check Active dir on the master domain controller if nearest dc fails.. try to resolve the name using windows locator broadcasting It's a lot of hoops just for a friendlier naming scheme. Mostly, you just don't want windows to have to do this work for you. Windows networking is more dns based, but it still has a locator service with a fairly complicated heirarchy of resolution attempts. Instead, you want the JDBC service to bypass the application layer and get that name resolved prior to it arriving at the windows locator service. Simply ask yourself - "how is the server going to resolve this name". Mark Minasi's "mastering windows server 200x" books have some great information on how windows goes about this process. Mark A.

Anyway, after sending him the contents of a few log files, it looks like he's traced it to a bug in the ColdFusion client variable purging system. Apparently there are bugs in this that cause connection leaks and it's slow which can cause a backup of requests. There is a hotfix for this at: http://www.macromedia.com/support/coldfusion/ts/documents/client_purge_hotfix.htm Apparently this wasn't included in the Updater? Also, there is a bug in the hotfix (!) which appears to mean that client variables are not deleted at all. This is to be fixed by another hotfix in the next few days but I am told it is better to apply the original hotfix in the mean time. So, if you are getting unexplained surges in CPU on an hourly basis (hourly from when the service is started) then this could be your problem.

CF7 100% CPU usage
Just installed CF7 on our Win2003 server a couple of days ago. Since then we've been having trouble with our site running slowly and certain large threads on our (in-house developed) discussion board timing out completely. I checked the CPU usage and, after a little experimentation, realized that accessing the large threads on our discussion board is what was killing the CPU with 100% usage. In 6.1 we never had this problem. I have to conclude that something on that page isn't working as efficiently in 7 as it was in 6.1. Is anyone aware of issues with 7 that would cause certain code that ran just fine in 6.1 to suddenly come to a screeching halt? Or perhaps someone might have an idea of something else it could be?

CFInsert and 100%CPU bug
I know Allaire denied it ever existed but in some circumstances CFUPDATE and CFINSERT can cause a 100%CPU usage problem. I'm wondering if anyone who has experienced this has solved it by applying CF4.5 Service pack or moving to CF5.0 I'm hoping to avoid the hassle of replacing 15 lines of code with an approx 140 lines in a CFQUERY Tristram Charnley ~~ Get the mailserver that powers this list at http://www.coolfusion.com FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Archives: http://www.mail-archive.com/cf-talk@houseoffusion.com/ Unsubscribe: http://www.houseoffusion.com/index.cfm?sidebar=lists

We've been having an issue with Verity eating up CPU cycles since upgrading, so if you've got any code relating to Verity in your code, you may check that. I'd recommend downloading the trial of SeeFusion (http://www.seefusion.com/) SeeFusion has a trace() method that you can invoke to dump messages to a SeeFusion Debug window. This is a very handy way of debugging templates in production--since the trace statements do not show up in the generated output. It also puts the execution millisecond timestamp next to each statement, so you have an idea of where things are slowing down at. -Dan ~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:234072 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54

RE: RE : Jrunsvc 100% cpu process
It will run happily on IIS and 2003. There are many things you can do to improve performance. I always start at the configuration level and work back to the code - unless I "know" there is something in the code that is causing the problem. Start with: Server stuff - ram, processor, unecessary services, network card and card configuration etc. CF Ap Server stuff - settings in the CF Admin, jrun.xml and jvm.config files - Tuning the JVM can be especially helpful with an error like this. IIS Stuff - try separate application pools or web gardens. Now I'd look at the code. As a rule - all of the stuff above should be handled on the installation of a new production server. It's amazing to me how many production servers are tooling along using the default installation parameters. Remember, default installation of windows, iis, Coldfusion and the like is designed to cover the maximum number of installation scenarios - not to be the optimal configuration :) -Mark -Original Message- From: Jean-Michel DE FILIPPI [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 21, 2005 8:17 AM To: CF-Talk Subject: RE : Jrunsvc 100% cpu process I've a lot of long requests, but I never use select * FROM ..

Check out your server connections in the file browser. Every so often the FTP or RDS connection would get screwy on me, and would end up in memory loss. Although restarting the app would fix it.

100% CPU on CF5 - but patch has already applied!
Hello all... I thought I would post this to the list, since my attempts to solve the problem have failed. I have run into an old problem. Well, sort of. I have the developer version of CF5 installed on my desktop at work, which is running XP Pro on a 2.8 GHz P4... and I am running into the 100% CPU usage caused by NTconsoleJava.exe - the ColdFusion Management Repository Server. But... here's the problem: I have applied the patches from Macromedia and deleted the logs, as according to: http://www.macromedia.com/support/coldfusion/ts/documents/tn18000.htm BUT I STILL HAVE THE PROBLEM!!! It's still doing it! Other than disabling the service, is there anything I can do to fix the problem? Has anyone run into this problem AFTER applying the patch? Is there another patch that I can't find?

Re: OT: SQL-7-Server piking to 100% CPU
Probably your most effective tool to debug this is going to be the sql profiler. I would do a google on something like "sql profiler optimize long running query" to get some ideas on how best to set up the trace. With that tool, you can have sql keep a log of all kinds of statistics, and then use the Index Tuning Wizard to analyze the trace. I've seen a single index change make a query that would churn away for minutes (using 100% CPU), go down to something that ran in under a second. Also, the query optimization routines that SQL Server uses are not always perfect...and I've had them change query times drastically from SP to SP (especially when we were using SQL 7)so it's a good idea to run traces like this regularly, and make sure that your indexes are optimized. Make sure you run the tools on another machine...as there is quite a bit of overhead associated with them.

RE: 100% CPU on CF5 - but patch has already applied!
Brian, Don't take this the wrong way. Have you checked your cf code and any queries that you are running? I have had problems of 100% usage and generally it was due to a coding error or very poorly written query. Since it is developer edition, you should know which templates are running when it occurs, so I would start there.

RE: 100% CPU on CF5 - but patch has already applied!
> It's not a coding issue. There wasn't any code running. > This happens on startup. No, the management service doesn't have anything to do with code. I know you asked for ways to fix the problem, but unless you're actually using the service, I'd just recommend that you turn it off. Perhaps you've enabled a server probe? I think that's handled by the management service, but don't recall for sure.

dll to correct 100%CPU due to messages in /mail/spool/
I recall a while ago there was a .dll which was supposed to correct a problem with undelivered messages in C:\CFUSION\\mail\spool\ causing CFServer to use use 100% of the CPU time. Can someone point me to it?
