Too many open files error -- using tomcat 6.0.14 on RHEL 4
We're seeing an error that we didn't see yesterday, but when we modified -Xmx settings for Tomcat, we no cannot get past the issue "Too many open files") and the sites on the server are not serving -- except this error. We've changed the settings back, but any restart causes the same issues.

HELP -- need to get Basic Authentication working (.htaccess) with Apache/Tomcat 5 to prevent access
I need to figure out a way to 'gate' access in a broad sense to the overall website on a test server. The site is all JSP, using Apache and Tomcat, but .htaccess doesn't work, as it appears that Apache hands off to Tomcat prior to doing the .htaccess check. Does anyone have a solution to this? This is only for a test server, so general access is limited. So I just want users upon first accessing the site to have to enter a username/password as a basic authentication to view the site... I need to get this done quickly, if it's possible. thanks, Kim :-)

Re: Does anyone have an approach to checking if Tomcat instance is UP?
Everyone -- thanks for all the ideas and feedback. We've attempted to take the approach with our health.jsp to check the major functions in our application -- so if we can do a database request, that checks a bunch of things - and returns without error lets us know that our application is functioning. We figured that since it was running through Tomcat (as a .JSP) that tomcat would have to be up to have the page respond... so we didn't worry about Tomcat itself. Should we? In this instance the health.jsp continued to work and report all was good, while the main index.jsp got an OutOfMemory exception. If I query the runtime memory, will that have caught the exception happening in in the index.jsp? So if I check the available memory or percentage and it's lower than whtever threshhold we establish, then we could return a 'down' condition... would that be a solid way to catch any further memory errors? We use a monitoring tool that has the automated checks for the application JVM and we can set different threshholds there -- but I've got to be able to have the check run by the load balancer know that the system is down -- and it does only a simple check against this JSP page, and then knows to fail over -- so while we are working to establish threshhold alerts with our monitoring application, we also want to ensure the load balancer fails over accurately as well... So all suggestions are welcome.

Re: Does anyone have an approach to checking if Tomcat instance is UP?
Tracy, The JSP does a call to a method in our app -- which if it runs, that means the app is up and available -- the method does a simple query against the DB and then returns a status of OK if the method runs through just fine. In our example from this weekend -- the health.jsp (which is the one that does this check) ran and returned a good result, but the main index.jspreturned the 500 error with the OutOfMemory exception. So that is what is confusing here. thanks, Kim :-) On 8/20/07, Nelson, Tracy M. <[EMAIL PROTECTED]> wrote: > > How is your JSP checking your application?

Re: Does anyone have an approach to checking if Tomcat instance is UP?
Dan, True enough, except then those queries would get held as a user session, and we don't want that -- which is why we have a 'skinny' health.jsp that checks our app -- and 'should' crash if there are any issues with tomcat or the application -- but in this case, the main pages were getting out of memory exceptions, but the skinny health.jsp was running just fine... which it shouldn't be if there are failures in either Tomcat or the App. We're using Application Monitor to monitor the app and tomcat JVM instances as well as the health.jsp response. But for the load balancer, which only uses health.jsp, that's what needs to pick up the problem and report accordingly so the load balancer will take that server out of the load balanced cluster.

Does anyone have an approach to checking if Tomcat instance is UP?
Hello -- We have a load balanced situation, and we have a JSP that runs and checks our application to ensure it's up and returns a string that the monitor app is looking for if all is well. Repeatedly, that JSP will work, but the site is down because Tomcat hit an OutOfMemory exception -- but our JSP (which is very small) still runs through it's process and returns that everything is happy. Our application is up, but the 500 error is an OutOFMemory exception. We need a fool-proof way of knowing that the site is up or not, specifically so the load balancer will know to stop routing traffic to a server when it's down, and we can have people taking a look at what happened and bring the server back online without loss of service from a user perspective. Any suggestions on how to accomplish this? thanks, Kim :-)

Re: Question with the Apache/Tomcat interface...
Here's what we figured out the issue was, after MUCH research... I'm providing it into the mailing list in case others have issues with Apache and Tomcat connection getting the error: Error connecting to tomcat. Tomcat is probably not started or is listening on the wrong port. worker=p2 failed errno = 13 As it turns out errno=13 is a permissions error. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=161049 was found to be the issue. This could have been induced by an update that was put into effect when the server lost power and rebooted. To resolve, I disabled selinux. Details below: Modified /etc/selinix/config to: SELINUX=permissive From SELINUX=enforced Executed "/usr/sbin/setenforce" 0 to put this into effect immediately. It will persist across reboots.

That's not what he was asking. Can a telnet client on some other machine connect to the IP address and port your've specified? This doesn't require a telnet server on the target system, it just verifies that something is listening for connection requests on that IP/port combination. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Rainer, What is your platform and what is errno 13 on your platform? ###how would I find out? our platform is Fedora Core 3 for this server. Can you confirm, that tomcat listens on the port your worker p2 is configured for (using netstat -n or a similar tool)? ###when I run netstat, it provides a bunch of results that I'm not sure how to interpret... do you know what I would look for here? Can you connect to the ip and port specified with p2 from your apache machine with telnet? ###we have telnet disabled on the server, as it is not secure. the two processes are running on the same server (apache and tomcat). thanks, Kim :-)
Question with the Apache/Tomcat interface...
We are running Tomcat 5.0.30 and Apache 1.2 using mod_jk, with workers.properties. It's been working just fine, no problems. But our ISP had a power outage, that forced a reboot on the servers. And now, one of the servers Apache/Tomcat link appears to not work, so that server is still offline. Again, we had no config changes, only a reboot forced on the server. The error I get in the logs is: Error connecting to tomcat. Tomcat is probably not started or is listening on the wrong port. worker=p2 failed errno = 13 But tomcat is starting up per our script as always -- again, nothing has changed... it just seems very wierd. we stop it, stop our app, start our app, and start tomcat -- we get no errors from teh tomcat startup... we have also tried stopping and restarting apache -- nothing seems to get past this issue -- again -- used to work perfectly, and we have made zero config changes. HAs anyone run into this occurring? thanks, Kim :-)

Re: Session hijacking with Tomcat/Myfaces - unable to fix it
It's a fundamentally bad security scheme to use the session-ID as the identifier for your users. Might be straight forward, but architecturally a bad choice if you *really* want a secure area. Kim :-) On 8/9/06, Tomas Hulek <[EMAIL PROTECTED]> wrote: The default Tomcat installation is prone to session hijacking. I would appreciate help how to fix it. The problem is that the session-id generated under HTTP (eg. for any JSF page) is caried over to authenticated confidential pages under HTTPS. Thus the session ID can be easily sniffed under HTTP, then misused after user logs-in under HTTPS. I believe it can be considered as a serious security bug. Scenario: 1) Tomcat and JSF, using Apache MyFaces. 2) A single application (context), using JSF pages 3) Some pages are public, and Faces servlet requests session ID on the first hit 4) Some pages are only accessible under HTTPS after authetication, as defined in web.xml: Secret part /secret/* secret_role CONFIDENTIAL 5) Form-based authentication is used for the login (again, defined in web.xml). 6) The user goes to the public part of the aplication, gets a session ID (under HTTP) 7) The user goes to a confidential URL, logging-in successfully. The same session ID is retained!!! 8) Anyone who knows the session ID generated in step 6 can reach the confidential URL. We have not found any straightforward way of making Tomcat regenerate the session ID once user swichtes to HTTPS. We tried many approaches, and all of them break some part of the JSF application.

Re: Tomcat Crashing -- how do I read the resulting hs_err_pid11598.log?
Martin, That's all interesting, but we're not running Fedora Core 4 -- we are running Fedora Core 3. Secondly, I've got this identical environment running in production without incident. This environment on this server "used" to run without incident until we had to replace the memory, and now it crashes -- same config I've got running fine in other places -- which is why I'm trying to figure out what's different. What I know is different is that this server has 4GB of RAM when all of our other servers have 2GB of RAM, so that is a difference. Otherwise, they run the same J2sdk1.5.0_03, all run Tomcat 5.0.30, and all run the same version of our application. That's why I was hoping to gain some insight from the PID file that got thrown to see what might be causing the issues -- do you have any suggestions on how to debug this environment to get at the root cause here? thanks, Kim :-) On 7/21/06, Martin Gainty <[EMAIL PROTECTED]> wrote: Kim- Did you see this catch this bit of legalese in tiny print Fedora Core 4 users are advised not to use the Java RPM provided by Sun.

Darryl, Yes I have the PID error file -- I just need to know how to read it. What was put into the catalina.out file is what I included in the original post -- I do have the PID error files also.

For most real-time client serving applications using any swap space to service any part of those requests is counter productive. It only makes sense if you are using the swap as some form of data backing store, but then you have to ask why not just leave it in a file anyway.

Tomcat Crashing -- how do I read the resulting hs_err_pid11598.log?
I'm running Fedora Core 3, Tomcat 5.0.30, in a two server environment, where we have an F5 load balancer and are doing session sharing at the Tomcat level. The box has 4GB of RAM on it, and has experienced a memory failure. We tested the physical RAM on the server, and it failed 2 extended memory tests, so we replaced the RAM. We also saw that the swap space was only at 1.5GB, so we upped that to 6.5 GB. Prior to this issue with memory, Tomcat ran just fine without error. Now, Tomcat runs for about 30-45 minutes and crashes. The catalina.out file has this: # # An unexpected error has been detected by HotSpot Virtual Machine: # # SIGSEGV (0xb) at pc=0xb79d032a, pid=11598, tid=1886555056 # # Java VM: Java HotSpot(TM) Server VM (1.5.0_03-b07 mixed mode) # Problematic frame: # V [libjvm.so+0x3b532a] # # An error report file with more information is saved as hs_err_pid11598.log # # If you would like to submit a bug report, please visit: # http://java.sun.com/webapps/bugreport/crash.jsp # so my question is: how do I read/interpret the hs_err_pid11598.log file so I can figure out what is happening here? thanks, Kim :-)

The name depends on which MPM your Apache is compiled with. Most likely it's the prefork MPM as that is default, but could be the worker MPM. -Dave - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Way to debug ports Tomcat is listening on?
