I received a maintenance release of IRIX 3.2.1 from Silicon
Graphics, which was to fix some system hangs and network
problems we experienced on IRIX 3.2 on our IRIS 140 4cpu
server system.

IRIX 3.2.1 has run for two days then it also crashed with a 
new type of condition.   This time CPU1 went into a mode of
100% kernel activity.  The CPU's 0 2 3 were basiclly idle.
User consoles started to lock up.  The network died.  If a console
which was working started a new shell it would die.  The system
console was active and allowed us to run osview.  However we could
not kill processes.  And a powerdown did nothing.  So we had to
reset the system.

SG still seem to have a problem in getting the multi processor
servers to stay up for more than a day or too.

We find it very difficult to work with it at the moment.  We are using 
the server to develop software in F77 for the mining and petroleum industries.

If others are also having problems please let
SG know so we can get them to fix it.

Thankyou
