If you host your own CF server, I'd contact someone like Mike Brunt about a
JVM tuning job. We have him look at our machines every so often and they
always run like magic after he's done a round of JVM tuning.

http://go2ria.com/

He's remarkably inexpensive relative to the amazing work he does - We
really thought we needed to added a couple more machines, he did his work,
now I think we can more than triple our load before we add any more
hardware...

(There are others who do this work as well - CF WebTools for example - I'm
just a big fan of Mike)

Cf is not looking for anything, as per my previpus explanatipn it is the
proxy port between the web server connector and jrun.

Re: Port 51011

2012-08-14 Thread Cameron Childress 

IIS proxies requests to CF on port 51011.

So it goes like this: The web browser sends requests to IIS on port 80,
then IIS hands off the request to the connector, which turns around and
sends requests to CF on a preconfigured port in the 51000 range.

Then CF replies to IIS and IIS replies to the web browser.

What is CF actually looking for on port 51011?

IN Cf admin you have a max number of concurrent requests. If all of
those requests hang, then cf will start queuing requests, which is
probably why your seeing 500.
You need to look at the hung requests and see why they are hanging.
Have you tried the built in server monitor ?
If you do not have this (requires enterprise edition) then try
fusion-reactor,. and also be sure you use the jdbc wrapper on your DSN's
to do JDBC traces.
the most common cause for hung requests that will not finsih is either
database activity or IO activity which are Native java calls which
cannot be killed automatically by CF's timeout.

Only CFM/cfc and related files are served by ColdFusion, your JS files
are served directly by the web server, so these would not contribute to
the coldfusion traffic or number of requests.
If those JS files contain ajax requests to the CF server, then this will
happen after the page renders in the client and the js has fully loaded.

Well, that's good news. As Russ mentioned though, they are not processed by

10x more traffic? Yeah that will hit you where it hurts for sure. The
first advise I would give is to look at changing you code to use the
Google hosted version of these libraries:

Yes, 10x traffic will do that. :)

This smells like CF is getting hung and IIS continues to send it
requests.
This leads to a dogpile effect on CF where it's still receiving new
requests from IIS but can no longer respond. This is usually due to a
problem with something getting hung up in your CF code, or with SQL. For
example, a SQL call that never comes back from the database, or some
CFHTTP calls that never hear back from their servers, or a CFLOCK tag
that's in a deadlock.

If this is in fact the problem - the best way to troubleshoot this is
install something like FusionReactor on the server and get a stack trace
while the error is occurring. This will quite literally give you the
exact line of ColdFusion code causing the problem. I'd bet a dollar that
it's one of the three things I mentioned above.

no it is not free, but there is a trial version, and you can also take it
on a monthly (SAAS) plan as well, which is reasonably priced.

This smells like CF is getting hung and IIS continues to send it
requests.
This leads to a dogpile effect on CF where it's still receiving new
requests from IIS but can no longer respond. This is usually due to a
problem with something getting hung up in your CF code, or with SQL. For
example, a SQL call that never comes back from the database, or some
CFHTTP calls that never hear back from their servers, or a CFLOCK tag
that's in a deadlock.

If this is in fact the problem - the best way to troubleshoot this is
install something like FusionReactor on the server and get a stack trace
while the error is occurring. This will quite literally give you the
exact line of ColdFusion code causing the problem. I'd bet a dollar that
it's one of the three things I mentioned above.

Re: Port 51011

2012-08-14 Thread Russ Michaels 

IN Cf admin you have a max number of concurrent requests. If all of those
requests hang, then cf will start queuing requests, which is probably why
your seeing 500.
You need to look at the hung requests and see why they are hanging.
Have you tried the built in server monitor ?
If you do not have this (requires enterprise edition) then try
fusion-reactor,. and also be sure you use the jdbc wrapper on your DSN's to
do JDBC traces.
the most common cause for hung requests that will not finsih is either
database activity or IO activity which are Native java calls which cannot
be killed automatically by CF's timeout.

Only CFM/cfc and related files are served by ColdFusion, your JS files are
served directly by the web server, so these would not contribute to the
coldfusion traffic or number of requests.
If those JS files contain ajax requests to the CF server, then this will
happen after the page renders in the client and the js has fully loaded.

This leads to a dogpile effect on CF where it's still receiving new
requests from IIS but can no longer respond. This is usually due to a
problem with something getting hung up in your CF code, or with SQL. For

RE: Port 51011

2012-08-14 Thread Steve LaBadie 

We deployed a new website several weeks ago.
The average number of jqueries served before July-19 was ~2000 a day;
now we are serving ~45,000.
 
The resources that are the most exhaustive are the following:
1.  /js/jquery.bxSlider.min.js 
2.  /js/jquery.nivo.slider.home.js 
3.  /js/jquery.colorbox_min.js 
4.  /js/jquery.tablesorter.min.js 
5.  /js/jquery-ui-1.8.20.custom.min.js 
6.  /css/jqueryUI.css

Also, the rich format of the new website is taxing the ColdFusion
engine.
When the website seems to stop, the number of connections to CF's port
51011 increase from about 5 (average normal) to about 500.
These are TCP connections that take minutes to clear. Some stay in a FIN
state (finishing) for a few minutes before actually closing.
CPU and Memory resources are steadily low when this hang-up happens
(therefore not a Hardware or an OS problem).

As Russ alluded to, ports in the 51000 range are used by the ColdFusion
Connector (that connects CF and the WebServer). So, getting alot of
requests via that Port may be totally expected, as long as it's requests
between CF and IIS.

Are you sure this is the CAUSE of performance problems? If you're seeing
those connections and just assuming "well, that can't be good", you
might be looking at a red herring here. you're real problem may lie
elsewhere.

In any case, when the CF Connector starts acting screwy, sometimes it's
best just to remove and recreate it. Otfen you won't know what went
wrong, just that it started working again.

Also - don't attempt to do that unless you know what you are doing,
which hopefully you do.

Re: Port 51011

2012-08-14 Thread Russ Michaels 

internally the iis connector has to connect to JRUN to service the request,
this happens on another port, generally referred to as a proxy request.
I do not know what port CF6 used, but this would be my guess as to what it
is.
If you have a look in the connector config file, it should show you the
port it is using.

I'm going to venture a guess and say that (a lot) more information is
necessary.

What kind of requests are coming through 51011?
What should they resolve to?
What is happening?
Error messages?
Other interesting behavior?

Or, perhaps better questions...

What are you expecting to happen that isn't happening?
What is happening that you don't expect to?

Port 51011

2012-08-14 Thread Steve LaBadie 

I have never encounter this problem before, but we are getting a lot of
request through port 51011 which is preventing our pages from resolving.
We are currently using MX 7 IIS6. We have been running with version 7
since it came out and have never had this issue arise before. Can anyone
give any insight as to what to do to remedy this problem?
