Slow ops - longest blocked for more than 9 hours!

I checked my dashboard this morning and am seeing an error that there are 146 slow ops and the longest one has been blocked for 35,896 seconds (not milliseconds!)

It also states that mon.petasan3 has slow ops.

 

How do I determine what is blocking these ops and how do I clear them?

I made a screen capture of the various charts if that helps at all:

This has been resolved. I got with one of the guys from 45drives and he restarted the ceph-mon for the affected node. Once restarted the health warning cleared.
