This definitely is a gluster/nfs issue. For whatever reasone, the
gluster/nfs server crashes :-/ The log does not show enough details,
some more lines before this are needed.

There might be an issue where the NFS RPC-services can not register. I
think I have seen similar crashes before, but never found the cause. You
should check with the 'rpcinfo' command to see if there are any NFS
RPC-services registered (nfs, lockd, mount, lockmgr). If there are any,
verify that there are no other nfs processes running, this includes
NFS-mounts in /etc/fstab and similar.

Could you file a bug, attach the full (gzipped) nfs.log? Try to explain
as much details of the setup as you can, and add a link to the archives
of this thread. Please post the url to the bug in a response to this
thread. A crashing process is never good, even when is could be caused
by external processes.

Link to file a bug:

Thanks,
Niels
