We have a client/server database product whose server runs under DU 3.2g.
Every couple of weeks or so we have a customer whose server process gets in
a "U" state which, reading man pages indicates "Uninterruptible sleeping
process". At this point the process cannot be killed (even with a kill -9)
and we have had times when the system won't even shutdown! (The RESET
button must be pressed.)
Does anyone know how/why a process might get in this state? Our engineers
are baffled. I know there are probably a lot of ways, but if anyone has
experience with just a few it might give us some clues.
Thanks!
