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@allspice) (gcc version 4.8.2 (Ubuntu
4.8.2-19ubuntu1) ) #54-Ubu
ntu SMP Mon Jun 9 22:45:01 UTC 2014 (Ubuntu 3.13.0-30.54-generic 3.13.11.2)
vendor_id : AuthenticAMD
cpu family : 16
model : 4

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.
