garbage-collecting

Hi,

There is a frequent occurence of FULL GC in our system. We are using Java application running on Tomcat server. Our application is running using internal load balancer setup. We are seeing lot of Full GC's in the server logs due to which the application is hung and Proxy errors are occured.

The Java parameter values we are using are: Webapp wrapper: wrapper.java.additional.4=-Xms382M wrapper.java.additional.5=-Xmx1024M Backapp wrapper: wrapper.java.additional.4=-Xms382M wrapper.java.additional.5=-Xmx1024M

The error found in webapp wrapper logs: INFO | jvm 1 | 2010/11/26 09:33:19 | [PSYoungGen: 1398460K->140291K(1514624K)] 4623364K->3491394K(5009920K), 0.7285303 secs] [Times: user=1.42 sys=0.00, real=0.72 secs] INFO | jvm 1 | 2010/11/26 09:33:19 | 68539.126: [Full GC DEBUG | wrapperp | 2010/11/26 09:33:19 | send a packet PING : ping

Tried to change the JVM values to increase the heap size. But of no use. I suspect that there could be some other reason other than these parameters which is causing the issue.

Can anyone please help me on this?
