Typically it's too late at that point. You might want to try these command line options to see what's happening to the heap (assuming that heap exhaustion is a factor): -Xloggc:<filename> -XX:+PrintGCDetails You can also use these to capture the heap if and when an OOME occurs: -XX:HeapDumpPath=<filename> -XX:+HeapDumpOnOutOfMemoryError - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
