Sun watchdog reset due to software?

Subject: Sun watchdog reset due to software?
We have a Sparcstation 5 running Solaris 2.6. When we run our
software which was working fine under 2.5 (also on SCO, Linux,
UnixWare and QNX) the machine does a watchdog reset.
We are compiling using the Visual Workshop 3.0 for Sparc. The program
compiles okay -- running it seems to kill the machine.
This is a used machine we bought, and I was wondering if it's a software
problem
or maybe something wrong with the hardware?
THE ANSWER:
NO!!!!!!!!!! (which is a good thing for us -- since we're a software
house). ;-)

renny,
Its most likely hardware. Essentially watchdog is not part of unix
kernel so ....

Check the archives of this list. Someone just gave a very good answer
to the question "what is a watchdog reset". It has something to do with
an interrupt that happens when interrupts are disabled (and not
expected). This causes the cpu to reset. The answer stated that
it could be either software or hardware.
That's all I remember.
