Hello,

I have problems with lockd on an NFS server (stock 2.6.17 kernel); I have
no easy test case to reproduce the problem, but after one to two weeks of
uptime the lockd process is simply stuck. It fails to shutdown
("lockd_down: lockd failed to exit"; afterwards the "[lockd]" thread is
still around and stuck in D state) and is otherwise unresponsive. No other
kernel messages are logged.

Only full reboot solves the problem.

Can you tell me
- if there is a known lockd problem? I could not find anything in the
archives, but maybe I have missed something
- if it may be a file-system-specific problem (reiserfs in the present
case)?
- what else can I do to provide more useful diagnostics?

Thanks and best regards
