[Bug 1505564] Re: Soft lockup with "block nbdX: Attempted send on closed socket" spam
Junien,
I faced minor issues on backport yesterday and today is holiday in
Brazil. I'll get back to this soon. Nevertheless, it is good feedback
that this "qemu-nbd" workaround is probably making the system more
stable.
I'll get back to you soon.
Thank you
Rafael

Title:
Soft lockup with "block nbdX: Attempted send on closed socket" spam
Status in linux package in Ubuntu:
In Progress
Bug description:
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.
Attaching apport files from 2 hosts below.
