Hi,
i have an issue with WMB V7001 on RHEL V5.6 a multi-instance Broker with all the broker files residing on NFS4 share.
whenever i start the broker i see the following message though i make sure all the ports are released gracefully once i stop the broker.
Feb 6 12:25:01 HOSTNAME WebSphere Broker v7001[30271]: (BROKER.EG)[1]BIP3144S: An error has occurred during HTTP listener startup: the specified TCPIP port (7844) is already in use. : BROKER.af8f7782-2e01-0000-0080-9b726dd80f93: /build/S700_P/src/DataFlowEngine/NativeTrace/ImbNativeTrace.cpp: 822: TomcatInstanceManager::startTomcatIfNecessary: :
And due to this issue i see multiple execution group processes running with same name and the parent PID of the duplicate processes will be 1 all the time and this happens to multiple execution groups on the same broker, and i have to kill these processes whenever i stop the broker again.
Any help/thoughts on this will be very helpful.
Thanks

Update your WMB runtime to latest version.
For future reference, consider redundant brokers rather than multi-instance brokers, when designing for fault tolerance, performance, or high-availability.
Geographically separate your redundant brokers.

Remember that on linux, ps reports threads and not processes.
So if you see multiple listings for the same EG, you may merely be seeing threads in the single eg process. |

if i am correct only ps -eLf returns all the threads and ps -ef returns the processes running. |

As a service to my friend Vitor, all my express opinions are mine, and others can certainly differ with them.
