IdM dispatcher is down - where/how to check the cause?

Hi IdM friends,

I am supporting a IDM customer and its IdM production dispatchers was stopped 3 - 4 times this month. When the dispatcher is stopped, I am able to restart it without any problem. I have also setup another dispatcher on the same server, the only purpose/job is to monitor the production dispatcher is working properly or not. Both dispatchers were stopped.

The IdM DB is running on a MSSQL load balance configuration with two DB instances and has a listener in the front.

I would like to know where to start when the dispatcher is dead again?

Best Regards
