During system shutdown I noticed an error about unmounting /var/lib/nfs/rpc_pipefs because it was busy. I checked /var/log/daemon.log and found these errors: Sep 12 16:30:03 smaug /etc/init.d/rpc.idmapd[10549]: start-stop-daemon: no matching processes found Sep 12 16:30:03 smaug /etc/init.d/rpc.pipefs[10562]: ERROR: rpc.pipefs failed to stop Sep 12 16:30:03 smaug /etc/init.d/rpcbind[10672]: start-stop-daemon: no matching processes found No pid file is written by /etc/init.d/rpc.idmapd, maybe it is the culprit of this error. Reproducible: Always
Can you reproduce with a current version?
