Review Comment:
   I think this log msg would be more talkative in case we log the name of the 
processor and the uuid of that to identify which processor threw the given 
exception.

Review Comment:
   This log line is useful, but I wonder if it can occur... Throw in unschedule 
definitely sounds like something to avoid.
