ABI & SMP

ABI & SMP

[snpe]

Hello,
   I have kernel 2.4.17 and abi 2.4.17 patch
I have used aplication (oracle sqlforms30, runmenu for sco 5, coff).
Hardware is Compaq Proliant 1600 with 2 processors.
If I use kernel with one processor all is ok, but with SMP kernel
I have problem.
Application work btw one hour and then I get segmentation fault.
I am tried unload moduls and load again without success.
After reset all work one hour ...

Please help
regards

Do you have any OOPS message or something like that?  Also a trace
(echo 0xffff > /proc/sys/abi/trace) would be nice to find out the
last emulated syscall.

This is oops (kernel 2.4.17 + abi-patch 2.4.17) :

I don't make trace now, because machine is production and I compile UP kernel
In next few days, I get obtain 2-processor machine (Dell, probably) and tried 
trace
