olaf_koehler I have the very same problem and discovered these are not crashes.
Indeed on our production environment this is related to Managed Availability (MA) that initiate the "Application Pool" recycling/"Watson Dumps" or even Exchange services "restart".

In event viewer, have a look in "Applications and Services logs >Microsoft > Exchange > Managed Availability > RecoveryActionLogs" and filter for events 2050 and 2051.

Events 2050 show MA triggered Exchange service "restart" or Application Pool "recycling" (even WatsonDumps...).
Events 2051 show the same, except the MA throttling prevented the system to do so.
