Sun Managers,

You might recall I posted some time ago about a problem with some
Sun-3's crashing with a "panic: bus error" message. The problem appeared
when some students started running a Finite Element Analysis application.
I received a bunch of replies mostly telling me to either upgrade
from SunOS 3.5 to 4.1.1 or put more swap space on the clients, (I had
erroneously stated that they only had 10Mg of swap, when in fact they
have 16Mg, sorry about that).

Well after spending some time playing around with core dumps
using some tips I got from "" it seems that the
software is exploiting some kind of NFS bug in SunOS 3.5 and thus
all my 3.5 machines crash, including my server.

Up until now there was no reason to upgrade the machines to 4.1.1
but it seems that I no longer have a choice, particularly since
the company which puts out this software does not support SunOS 3.5
Dems da breaks :-(

I'd like to thank everyone who took the time to respond to my plea
for help. They are (in no particular order)...

Thanks a bunch!
