I am working on a websphere 6.x ND under RHEL.
Under normal conditions I see 1 dmgr process and 1 nodeagent process when I carry "ps -ef | grep java"
Often when I try to shutdown processes using "stopManager.sh" or "stopNode.sh" I get no response . When investigated java processes, I see 2 nodeAgent and dmgr processes which is very strange. I had to then kill them using "kill -9" to get everything shutdown.
How can I trace and rectify this problem?
