Thank you for testing!
A couple quick checks before really digging in: how 
big is the cache, and how much data is bonnie++ trying to slug around?
I also assume you don't have inaccurate entries for the realm in question 
in your CellServDB, but active confirmation is good.

This looks similar to what happened when I was running with a comically 
small cache, and never got back to after making my cache more sane.
