Question

ColdFusion 9 sites going down regularly once per day

Hello,

I'm new to the forum, so please bare with me if I have not provided the proper details or in the desired format.

Problem:  Daily, usually in the evening or early morning hours, USA time, our Cold Fusion sites are found down (4 sites, plus the default admin, cf instances) all connected through IIS and the Cold Fusion sites are configured to run as a Windows Service. 

Resolution:  Start the sites via jrun.exe or start them via Windows Services (services.msc) and it works fine, no further issues until the next problem occurs again later.

System: 
Windows 2008 Enterprise 64bit
VMware client running on VMHost - HOST info:  VMware ESXi 5.1.0 64bit, 1 CPU, 2 cores assigned.  6GB of RAM.  VMware host reports less than 50% CPU usage and memory across multiple VM Clients (Guests), no spikes of note.
Cold Fusion 9 64bit

Cold Fusion: 
Server Product  ColdFusion 
Version  9,0,1,274733   
Edition  Enterprise   
Operating System  Windows Server 2008   
OS Version  6.1   
Adobe Driver Version  4.0 (Build 0005)  

Server has one a week backups, once monthly bounces, patches applied one a month on the server.  We have a production service, much higher usage, no problems.

Environment:  Dev/test server, small team of users

Users starting the service/sites via JRUN, have admin rights on the server.

Storage is configured as SAN, as the F:\ drive on the server (17GB of 300GB free).  No known processes are running at this time.  Windows Security, Application, System, and Setup logs show only one error:

"The description for Event ID 0 from source ColdFusion 9 ODBC Server cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

ColdFusion 9 ODBC Server@LOCALHOST,ErrorCode=2300,ErrorMessage=Network problem, connection unexpectedly closed by peer"

Anyone have any thoughts as to what I can try or how can I track to see what is happening when this occurs (other than physically watching for it to happen) or if there is a known issue I haven't found?

Thanks so much,

DB

Hi Dean,

Perhaps there will be some useful information in some CF logs.

[CF]\runtime\logs server or [Jrun]\logs multiserver coldfusion-event.log & coldfusion-out.log

check for -

•java.lang.OutOfMemoryError: GC overhead limit exceeded

•java.lang.OutOfMemoryError: Java heap space

•java.lang.OutOfMemoryError: PermGen

•java.lang.StackOverflowError:

•java.lang.OutOfMemoryError: Out of swap space

CF9.0.1 so perhaps Java 6 in use? CF9 some update levels (9.0.1 being one as best I recall) officially

supports Java 7. It might not be much of an upgrade to change from EOL Java 6 to EOL Java 7 but could help.

As I recall CF9 does not support current Java 8.

HTH, Carl.

Hi Carl, thank you for taking the time.  Will engage developers to consider the same suggestion to upgrade.  Production running on like configuration/hardware has zero issues.

The only recurring error I see in the event log (cfusion and all configured sites) is:

error (JRun Service: ProxyService [jrun.servlet.jrpp.JRunProxyService@7b0acf26]) JRunPRoxyServer.invokeRunnable:

java.lang.IllegalStateException

at jrun.servlet.JRunResponse.getWriter(JRunResponse.java:205)

at jrun.servlet.JRunResponse.sendError(JRunResponse.java:597)

at jrun.servlet.JRunRequestDispatcher.invoke(JRunRequestDispatcher.java:328)

at jrun.servlet.ServletEngineService.dispatch(ServletEngineService.java:543)

at jrun.servlet.jrpp.JRunProxyService.invokeRunnable(JRunProxyService.java:203)

at jrunx.scheduler.ThreadPool$ThreadThrottle.invokeRunnable(ThreadPool.java:428)

at jrunx.scheduler.WorkerThread.run(WorkerThread.java:66)

...this is a recurring issue in the logs.  I regret that I did overlook it as a possible cause, but is it the error I should be focusing on?  This is the only error that recurs in the logs

and of course in the outlog:

Information [scheduler-0] - Run Client Storage Purge recurs about every 1 to 1.5 hours

In the production system, the output is pretty much the same on the outlog, but the event log does not have this above issue.

And again, I was focusing on general cold fusion since all sites cashed, but when I started looking into the extra sites, I found this:

javax.servlet.ServletException: ROOT CAUSE:

java.lang.OutOfMemoryError: GC overhead limit exceeded

at cfact_scrolling2ecfm421729402.runPage(F:\inetpub\wwwroot\_Common\act_scrolling.cfm:8

I'm checking the GC settings now and will adjust and test.

Anything else you might suggest?  And thanks again.

Dean

Hi Dean,

Following up this:

JRunPRoxyServer.invokeRunnable java.lang.IllegalStateException

I searched and found this old CF9 thread where that turned out to be something in CFC code.

Here is the post. See details refering to  - changed the following in my application.cfc

<cfset This.Clientmanagement="false">

https://forums.adobe.com/thread/776671

I see you have this:

java.lang.OutOfMemoryError: GC overhead limit exceeded

JVM configuration can sometimes help with that.

Regards, Carl.
