A heads in case anyone else has seen this problem.

Anyone noticed random faults on any sun4c machines when running process
intensive apps?

I'm getting random faults[*] when running long compile sessions. This
machine was running 1.6C until recently quite happily without problems,
though I didn't tax it that much before. I've recently upgraded to a 2.0
snapshot from releng.netbsd.org (can't remember date), with the kernel and
comp.tgz upgraded to the 200405100000 snapshot to see if they make a
difference. They didn't.

I'd assume hardware errors (parity etc.) would manifest themselves in
dmesg as they should cause a hardware trap?

Machine is IPX with 36MB RAM, unconfigured NELL and FSBE/S card. dmesg
attached. Similar installation on sun4m has shown no problems so far.

What should I be looking at to help diagnose this? I'll start looking at
core dumps if anyone has noticed this, but my guess is that this will be
random. A sun4c MMU issue again?

Christian

[*] Faults appear to be SIGSEGV, SIGILL, or SIGBUS. Re-running the compile
succeeds.
