Description

ResolutionMonitor.run() catches a general Exception and logs them no matter what.
It should explicitly catch the InterruptedException and exit gracefully.

Attached patch, catches the exception and logs a one line warning instead of whole stack trace.

No tests, I manually checked logs and dont see strack dump as earlier.

I think InterruptedException should be caught inside the loop so that the ResolutionMonitor could check fsRunning and decide what to do based on its value.
And there should be no messages higher than debug level, imo.
