Hi,
about my problems with nfsserver (see message "nfsserver hangs randomly" on this list) I can see this errors on /proc on all nfsd process:
# cat /proc/proc_number/Status | grep -v State
State: D (disk sleep)
What's it?
It's what the parenthetical says: A process sleeps in a D state when it's waiting for disk I/O. In practice, it is not necessarily a disk per se that's being waited for, but what all use of D sleeps have in common is that the event that ends the sleep will come very quickly (well under one second). When this doesn't happen and a process is seen to persist in a D sleep, it's a de facto sign of a problem. D sleeps and all sleeps at internal priority less than 0 cannot be interrupted by signals.
My problems wiht nfsserver is related below:
