Unkillable Samba on Irix

[Andrew Klaassen]

A couple of days ago, I was trying to kill Samba processes on an
Irix box, but was unable to do so.  Any smbd process (but not
nmbd) would go into an uninterruptible sleep, waiting for some
sort of event which it never received.  'ps' reported that all
smbd processes were waiting for the same event number.

The file systems on the box seemed fine; this didn't seem to be
the symptom of an unresponsive disk.

There didn't seem to be any NIC problems; other traffic wasn't
affected.

What else would smbd get hung up like that on?  Why just smbd,
not nmbd?

Details:  Irix 6.2; Samba 2.0.7.  Nothing interesting in system
log; didn't think to look at Samba log; has never happened
before (that I know of).

CC me, if you would...
