Alerting engine fails after 2 months in operation

mhase

Hello,

I have got a stability issue with SolarWinds Orion NPM 8.51 SP3. After about 2 month without a reboot or restart of the Orion services, I start receiving the following error in the Windows Eventlog:

 

Also, as soon as this error occurs, SolarWinds Orion stops raising or resetting alerts. A restart of the alerting engine fixes this problem, but I do not want to set up a scheduled task to do that.

Has anybody an idea, what might cause this problem?
