All,

We had an issue that the queue manager stopped and remained in status ended unexpectly ...

We had to restart it again, but have no clue why it ended.

My questions are:
- Where can we find more detail about why it ended? In the error logs we only see errors about connections that could not be made and channels that ended. --> Should not bring the QM down I'd say.
- We are missing a couple of error logs (see below), why can that be?
- Can we enlarge the error logs size or make it linear?

Some extra info:

What I noticed in the logfiles:

AMQERR03.LOG.backup.log: starts at '08/13/07 05:04:28' and ends at '08/14/07 02:44:41'
AMQERR02.LOG.backup.log: starts at '08/14/07 08:36:11' and ends at '08/14/07 08:53:43'
AMQERR01.LOG.backup.log: starts at '08/14/07 08:53:44' and ends at '08/14/07 08:59:51'

So as you can see we're missing the errors between '08/14/07 02:44:41' and '08/14/07 08:36:11'.

And 'AMQERR02.LOG.backup.log' starts with an error 'Channel program 'SYSTEM.ADMIN.SVRCONN' ended abnormally.' referring to an earlier error. (ACTION:
Look at previous error messages for channel program 'SYSTEM.ADMIN.SVRCONN' in the error files to determine the cause of the failure.)

So I suppose we're missing the logs to get the actual root cause.

Normally the other errors that can be found, shouldn't result in Q manager going down.

A million thanks for reading this qtn.

You don't say what version of MQ you're on, but a lot of those FDC probes are claimed as fixed in some of the v5.3 CSDs.

If you're not on the latest version, you might want to update.

Hi

Search the probe ids in google and get it..

I suspect you restarted your machine with out shutting down your queue manager
Thanks and Regards

Thanks for taking me to the right direction.

Looking at the probe id's I also can see the system was low on kernel resources.

I will also take a look what patches that are available.

To all,

Anyone an idea why we have a gap of couple of hours in the error logs as described above ?

Please don't post in big letters.

Maybe there was nothing to log during that gap.

That is impossible, because it was logging every quarter of an hour several channel errors which could not connect.

Can it be a consequence of circular logging ? I would think that it then deletes the oldest log to start a new log, but it did delete one in between I suppose.
