Hi,
One of our xenserver 6.1 running
ovs-vsctl (Open vSwitch) 1.4.2
Compiled Nov 23 2012 12:41:37
was showing NFS related error as it was not able to communicate with NFS.
in kernel.log it was showing stack trace with ovs pid in stack.
Can some one tell me does this stack trace show any issue with ovs.
