Event Viewer logs are flooded with unnecessary Door healtService errors (Event ID 4506)

Question

Hi Everyone,

We are seeing our event logs being flooded on 2 of our DB servers.

We are trying to identfy waht can be the root cause for so many errors.

Does this maybe have to do with too many databases on these SQL servers of which none are excluded from monitoring so causing issues for the SQL MP that needs to monitor/process more than the maximum number of DB’s per SQL instance?

Your advise is much appriciated!

Best regards.

Hi Kadam, Sushanth

there can be various reasons for this behavior, one of which could be the huge amaount of data sent to the agent for processing. What is sure though is that this hsould not happen.

I would say that the very first troubleshooting steps in this case would be to clear the agent cache and see what happens afterwards.

This is also suggested here, under Scenario 1:

Troubleshoot gray agent states in System Center Operations Manager

Please make sure also that yyou disable the workflows (rules, monitors, discoveries), which you don't really need respectively remove the management pack if it is not used.

Please complete the Health Service flush and then post back the events after restaring the agent in case the issue still remains. Please post als other events, which might be related to this behavior.
