Integration

I am getting the below error while deploying some soa applications in WLS 10.3 on solaris platform.As a workaround,
the server instance has to be restarted everytime i make the deployments when i face this OOM situations.
usually i face this issue after first deployment onwards.
So, everytime i make the next deployment the server instance has to be restarted before that.

The server is configured with 1Gb JVM and runs on JRockit jrrt-4.0.0-1.6.0.
MEM_ARGS="-Xms1g -Xmx1g -Xgcprio:throughput -Xverbose:gc -XX:+HeapDumpOnOutO
fMemoryError -XXcompressedRefs:enable=true"

Can anybody please provide any pointers to track/solve this issue?
