Hi NFSD developers,
I've found what I think is an interesting problem that occurs on single-CPU machines as far as I can tell.
Basically the following snippet will occasionally loop forever printing that one thread is still running. Further
attempts to run "/usr/sbin/rpc.nfsd 0" don't help.
/usr/sbin/rpc.nfsd 1
/usr/sbin/rpc.nfsd 0
while [ ! $[`cat /proc/fs/nfsd/threads`] -eq 0 ]; do
echo $[`cat /proc/fs/nfsd/threads`] still running
sleep .1
done
I've not looked a whole lot at it. It appears that although the paths calling svc_set_num_threads synchronize on nfsd_mutex, the code doesn't seem to try waiting on the number of threads to reach the desired count.
What do you guys think?
Thanks.
