Public bug reported:
We do see frequent crashes of rpciod on Karmic with nfs4 mounts. This happens
on different clients (all with karmic),
A reboot if the client is needed afterwards.
The mountpoint:
filer.server.physik.uni-muenchen.de:/home /home nfs4
defaults,_netdev,auto,sec=krb5p,intr,bg 0 0
It is maybe related to some hangs we observe with the nfs server (maybe a
network problem). On jaunty it just hangs and recovers, on karmic there is a
crash.
The following could be found in /var/log/messages:
