Bug Description
Some of our nova compute hosts regularly freeze, sometimes for a few hours, with kern.log getting spammed with:
block nbdX: Attempted send on closed socket
and a few "CPU soft lockup" messages (see attached log). This clears up when the queue gets cleared, eg :
block nbdX: queue cleared
trusty hosts with kernel version 3.19.0-30-generic.
