Hello Marinus,

Are you referring to updating PRTG or did you install latest Windows updates (also)? In any case, please send us logs using "Setup | Contact Support" and mention this knowledgebase thread in the ticket text as well.

Kind regards,

Erhard

Windows update were installed on the 24st of July and the first problems occurred 26 July 18:43u. A stop/start of the service resolves the problem, but most of the time within 24 hours it happens again. I just made the "ticket" by Contact Support option.

Cause is a lack of Memory, because of the Dynamic memory setting in HyperV.

Hello Marinus,

Right, memory should be fixed instead on dynamically allocated. I think you also have support case open with a colleague of mine, right?

Kind regards,

Erhard
