(Would that have made a difference in your case?) Not sure. Of course I was just "looking for a solution". So once I figured out that rpc.statd was missing I went looking for how that came about. But as it was the prime culprit was "lockd is misbehaving". With a better error message you can shift the blame away from your part of the system. :-) > > second?) timeout in nsm_mon_unmon and the big backlog of requests that > > result in the same call and timeout that frustrate the client... ) > > The -ECONNREFUSED case? > > I'm not sure why it retries there. Maybe just to allow stopping and > starting rpc.statd (e.g. for upgrades) without failing operations? Not sure IF it was retrying. Maybe not. But starting "google-chrome" with 40 open tabs didn't progress to any tabs loading inside the half hour that I was looking for why this was happening (unable to google for a solution).... So in the meantime it was constantly spewing the error message, rate limited to 10 per minute....
