@Serge, As mentioned in #1 the cluster is running Precise + Essex. Unfortunately I cannot consistently reproduce the problem, however the problem has been recurring approximately once per month.
As mentioned in #5 I think that perhaps nova-compute is attempting to query libvirtd and libvirtd is not responding. Since the query doesn't seem to time out nova-compute "hangs" waiting for a response which will never come. I can only query the system after the problem occurs and I only have current state and log files to try infer the problem. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to nova in Ubuntu. https://bugs.launchpad.net/bugs/985489 Title: nova-compute stops processing compute.$HOSTNAME occasionally To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/985489/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
