MOM 2005 Management Server Agent Stuck Queue
MOM 2005 Management Server Agent Stuck Queue One of the nicer aspects of MOM 2005 is its agent’s ability
to cache information incase there is a loss of network connectivity. This ability is available to both
the Agents as well as the management server. The sizes of the Queues space are easily changed under the
global settings for both the agent settings and Management server Properties when you right click on the
global settings icon under the administration folder in the MOM Administrator console.
I would recommend keeping the default settings for the queue size or increasing it in small increments
of a few megabytes as needed. I would not recommend having a queue larger than 90 megabytes for the
Management servers and no larger than 8 megabytes for agent computers. Doing so could introduce other problems.
We had been trouble shooting a problem where our management server queue would fill up.
Using performance monitor I added all the management servers Queue Space Percentage Used counter
to see what percentage of the queue space was used. To my surprise all the Management servers queues
were either 85% in use or higher. It stayed this high even when the mom service was restarted properly
over an hour or so. This is where I was introduced to the problem of a 'stuck queue', where something
in the queue has caused the agent to not process items/transactions after a certain point.
The fix is to clear the queue or cache, by stopping the mom service on your management server and then
delete the folder
c:\documents and settings\all users\application data\microsoft\microsoft operations manager\*your management group name*
Then restarting the mom service will recreate the folder and files.
