JVM keep doing garbage collection for WEBLOGIC

languages and scripting — Tue, 28 Feb 2006 05:25:00 GMT

Hi,

I have encountered a problem with weblogic with the HPUX JVM.
Basically the JVM is doing GC quite often.

Currently the weblogic server is performing continuous NORMAL garbage collection. Approx average of 1 normal gc every sec.

Let me ask the question here and hope that you guys can help.

1) Why is it performing continuous normal GC? What causes it? How can I find out why? Any troubleshooting steps?

2) I know that continuous GC is taking place. The average CPU and meemory usage is very high. What will you recommend?

Any comments welcome!
