System Crash

QNX Newsgroups (Archives) comp.os.qnx

Hi,

We are working with a Intel based industrial PC system and QNX 4.25.
At the system are running several processes, also processes to aquire
and compress
very large images and different audio sources. That generates a big
amount of
PCI DMA requests and interrupts.
At the moment we are working with a Celeron 433 Mhz with the older
processor
kernel technology (kathmai) and 66 Mhz system bus clock rate. The system
works continously and very reliable about weeks and months without
control.
With the actual processor generation with coppermine
kernel (PIII and Celeron, same and higher processor clock rate and
100 Mhz system bus clock rate) we have a problem:
Some minuts after system the processes die one after the other with
“Terminated (SIGFPE) 0x…”. This problem includes QNX system
processes and
our own processes.
Sometimes we had immeditly system reset.
But we have never seen the proc-managers kernel dump.
The same problems we also had with other prpcesses, e.g. ALSA audio
interface.

Has anyone experience with this problem or an idea to solve it.

With best regards

That’s VERY odd, to my knowledge none of QNX processes
used floating point instruction. However a division by 0 (integer) will
also generate that signal.

Why would all processes die in such a way is beyond me. The only thing
that comes to mind is a corruption in Slib (which is shared amongst all
processes)

Do you use some special/custom hardware. Have you tried different
motherboard (with different chipset)

Can you pin point which software triggers this?

Sometimes we had immeditly system reset.
