[Matt Fischer]

** Description changed:

- Hi I find that every 2 days or so I loose part of my cluster.

  It seems that openvswitch is crashing... The only message left on syslog
  is as follows:
  
  syslog:Jul  1 22:52:32 blue-compute kernel: [530482.190688] ovs-
  vswitchd[1935]: segfault at 0 ip 0000000000459110 sp 00007fff85804758
  error 4 in ovs-vswitchd[400000+133000]
  
  And this is the last message. I'm unable to reboot gracefully. I have to
  reset. (This can be because ceph not giving up also).
  
  And I can see a lot of traffic going around in the network. There so
  much traffic that some lowend routers/switches fail. Can be because
  another problem (machines stalled because the ovs fault and others
  trying to connect. Maybe it fails because much traffic). But I tell this
  for completeness.
  
  Now some info:

  I can attach full logs but I think there's nothing useful because only
  one line referring the problem.

  NOTE: restarting ovs does not solve the problem.
