CLR_SEMAPHORE & CXPACKET wait types I ran sp_Blitzfirst, and it threw back CXPACKET and CLR_SEMAPHORE waits as the top waits for my SQL server. 

I know how to fix CXPACKET waits, but how do I go about fixing CLR_semaphore waits?
Ignore that wait type CLR_semaphore - its a benign wait type to be filtered out as per Wait statistics, or please tell me where it hurts
