Public bug reported:

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:

Linux version 3.13.0-30-generic (buildd at allspice) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) ) #54-Ubu

Ubuntu 14.04 LTS (server).


ovs-vsctl --version
ovs-vsctl (Open vSwitch) 2.0.1

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.
