Hi,

Sometimes when we stop and start our brokers we get loads of nullpointer exceptions in syslog.user. This is an excerpt:

Apr 29 11:46:32 node203 WMQIv210[110842]: (QS12.HCDP_Tivoli)[1]BIP2203E: An execution group has encountered a problem whilst starting. : QS12.e9777288-ee00-0000-0080-c828893f66ca: /build/S210_P/src/DataFlowEngine/ImbMain.cpp: 502: main: :

It looks as if all the pubsub internal subscriptions are knackered. When we get into this state we have to restore the broker database as it seems to be corrupted. There doesn't seem to be any correllation with any specific action we're carrying out either...

We're using WMQI 2.1 CSD3 on AIX.

Anyone ever seen this?

Regards,

Derek.
