Every now and then, our Exchange Mailbox sensors generate this error; Timeout caused by wait for mutex (code: PE035).

The errors disappear after rebooting the target server.

PRTG version: 14.1.8.1371+ Target system: Windows SBS 2011 Standard x64 / Exchange 2010 SP1

Any idea on how we can prevent these errors?
