[Bug 1336555] Re: ovs-vswitchd segfault every 2 days

[Elias De Coninck]

Hi,

I have the same problem. There is just one difference: I'm using ubuntu
12.04 with linux kernel 3.13.

When the crash happens I can no longer access virtual machines. If I
restart neutron-plugin-openvswitch-switch the communication to vms is
restored.
