Kernel threads, yes.
From time to time one of them changes in to the 'D' (Uninterruptible
sleep) mode. Once it happens on a particular node it is also
impossible to mount any nfs exports on this node, which seems
logical since the nfs client uses the portmapper.
Are you able to kill those kernel threads ? Something like:
killall -9 rpciod
I seem to remember that they are (re)started as needed, but my
recollection of the NFS implementation on Linux is somehow hazy.
Probably the best place to ask is the Linux NFS mailing list...
