Hi There,
we faced one issue in production where MB service was giving timeouts.
We restarted EG followed by broker but it dint resolved the issue.
That particular EG calls two database(one by one and DB is common for all EG's). We checked with DBA but no issue observed there also.
Finally we observed that some messages are piled up in SYSTEM.BROKER.TIMEOUT.QUEUE and once we clear that queue service started running fine.
User logs also suggest nothing.
What could be the issue here. |

The issue is that you don't know the details of the service you are supporting and are just restarting things in the hope the problem goes away by magic.... 
Find out what the service does, what resources outside of the broker that it uses (e.g. web services). Are they working normally - were they down for a period?

This service uses store procedure call to connect to database.
And we have checked connectivity using mqsicvp command and it was working.
So my only doubt is whether actually clearing system.broker.timeout.queue resolve the issue or it was just coincidence that at the same time somebody from dba (they dont reveal the details) done something.
And if clearing queue resolve the issue then how. |

What is in the syslog?
Why would clearing a timeout queue stop further timeouts?
Clearing a timeout queue means you are discarding those transactions - so I hope you have investigated each and every one to ensure no business impact?
