[Wylug-help] D uninterruptible sleep (usually IO) WAS: NFS woes

[Dave Fisher]

 ... mmm ... still no solution, but one intriguing bit of diagnostic
info.

ps reports:

nfsuser       658  0.0  0.2  1936  796 ?        D    19:13   0:04 /usr/sbin/rpc.nfsd

indicating that it is in "D uninterruptible sleep"

... so, unfortunately are several dvd writing processes like growisofs
and mkisofs (thereby preventing all access to the dvd writer).

Is there any reasonable way of waking the damn things up and killing
them off?

Dave
