WebLogic OutOfMemory

[weiyue]

Hi,
I experieced a OutOfMemory problem which causes JMV crash.
Our web server runs on HP UNIX 11, jdk131_09, and WebLogic 6.1 environment. We used Java options -native -XX:_ServerApp -Xoptgc -Xmn160m -Xms512m -Xss512m -Xss512K and -server -hotspot -Xmn160m -Xms512m -Xss512m -Xss512K.

We run into this problem even if the server is not used.

The garbage collection log shows that for type -1 connection (recycle young generation) the server works fine;
the server crashed when it tried to triggle type 5 garbage collection to recycle old generation memory.

I would be very appreciated if you could help us out.

Here is our exception info:

941 ! weblogic.rmi.internal.dgc.DGCClientHelper::getHeartBeats()Ljava/util/Vector; (223 bytes)
