Hi,

In one of my windows NT server MQ 5-0 is running, there is one QM in the server, often I am facing the problem AMQZLAA0.exe is taking 100% CPU usage, because of that some of the channels are going down,

Can anyone provide the solution to this problem.

Thanks in advance

Chandu

Let me get this straight: you are running Windows NT with MQSeries 5.0 on it?

What does EventVwr say? What do the queue manager logs say?

Upgrade. WMQv5.0 is really, really old and also flaky. I do dimly remember seeing this kind of looping problem.

If this isn't an option (and if you're running NT 4 the site clearly isn't bothered by ancient software) and this has just started happening find what changed on the server and reverse it.

Or if the process loops when the channels go down, stop the channels going down!

WMQv5.0? Seriously? It wasn't that good when it was new. Why not go to WMQv5.3 at least???

(Back when 5.anything was still an option of course. That boat has now sailed. And sunk.)
