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
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.
