I can give that a try. One thing I forgot to mention, I don’t see anything strange in the logs either. No OutOfMemory exceptions no permgen errors, nothing unusual (notice I’m not saying no errors at all J ).

Without knowing enough about your app, here's a wild guess. Add

-XX:MaxPermSize=256m

directly after your -Xmx setting for heap memory.

Hi all,

I’m having an issue in our production environment. I have two servers (vm’s w/ windows 2008 r2 64-bit) running two instances each. The servers are load balanced by a hardware load balancer that pings the app on each box every minute to determine if it is still up (because of the way our app works, this creates a session). After about a week of uptime, the each app instance seems to just stop responding to requests one at a time until no instances respond any more. The java processes are still always running, but nothing responds. I recently bumped up the mem. on the apps to 3G each, to see if that would help, but the same problem occurred. Any ideas why this might be happening? It’s not good. Below is a sample of the app switches…

-WOPort 2001 -WOCachingEnabled YES -WODebuggingEnabled NO -WOOutputPath c:/logs/log-1 -WOAutoOpenInBrowser NO -WOAutoOpenClientApplication NO -WOLifebeatInterval 120 -WOLifebeatEnabled YES -WOLifebeatDestinationPort 1085 -WOAdaptor WODefaultAdaptor -WOWorkerThreadCount 8 -WOListenQueueSize 128 -WOWorkerThreadCountMin 16 -WOWorkerThreadCountMax 256 -NSProjectSearchPath () -WOSessionTimeOut 1800 -WOApplicationName eGM -WOMonitorEnabled YES -WONoPause YES -Xmx3g -WOAllowsConcurrentRequestHandling YES

Thanks.

-Mike
