apport information ** Tags added: apport-collected trusty uec-images
** Description changed: Hi, 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. Note that timestamps from kern.log appears to be wrong, it looks like the messages are being held, and then all delivered at once when the kernel unfreezes.
