Strange thing on tomcat "ps old gen" memory

Question

It happend something strange.

I have a server ubuntu 8.04 LTS Jvm 1.6.0.24

Everything run ok in test mode.

When i release the server to the users (i use mod_jk to redirect input from apache), it runs well for a while and then in few seconds the PS OLD GEN memory (1.3 GB) fills up and make tomcat unresponsive.

I checked memory leaks and thread leaks in the application, but everything seems ok.

Has some one experienced something similar ?

Thanks

How did you check for memory leaks? – fglez May 31 '12 at 11:04 — fglez, May 31 '12 at 11:04

Tomcat MemoryLeakProtection doesn't detect every possible memory leak.

I recommend you to actively check for a memory leak getting a JVM heap dump when problem appears and analyzing it.

There is plenty of information in SO to help you with the task
