CPU usage 100% by core server service



Since the last update the CPU usage of the PRTG Core Server Service is going through the roof.

I only have 16 sensors, just ping, rdp, pop3, smtp, ftp and http (not http advanced) at a scanning interval of 5 min. I am using a cluster, but even if I shut the failover server down it remains on 100% CPU usage. The same high cpu usage is also at the failover node.

After restarting the server CPU usage is back to normal for a few minutes. Then it goes to a 100% again. How do I solve this?

Thank you!

EDIT: We are already investigating the causes for the high CPU usage and an update including a bugfix can be expected this week!
