Thanks, I'll do that. Is it possible/likely that this lower op-version is
also causing the issue I posted on gluster-users earlier: 0-rpcsvc: rpc
actor failed to complete successfully

Any pointers on that would be greatly appreciated, since we've had multiple
occurences of this since Sunday, three today only.
Thanks,
