heap dumps Out Of Memory

Out Of Memory


If you receive OOM error in the SystemOut.log.

First you take a thread dump, heap dump.
take 3 dumps each with wait time of 1 min.

analyze the dumps and you will know what, where and how you received the OOM.

Also check if you have recieved any other error message like Thread hung , ConnectionWait time...

Also is there any other process that using lot of system resorce?
Check the Top and Sar -a command. it will give you memory usage on the system.

enable Verbose GC, for better memory management.
