I'm not a Unix guy so I really need some help on this. We have an NC machine post processor that runs on an old HP Unix box. Over the past few years, we have been migrating away from this machine so we haven't used this post for several years. We now have a need to to use this post processor again but we found that it no longer works because it fails with the following error:
Pid 4408 received a SIGSEGV for stack growth failure.
Possible causes: insufficient memory or swap space,
or stack size exceeded maxssiz.
Memory fault(coredump)
We did some research and found that this the last time we used this post processor was back in 2009. We took the last file that posted successfully and ran it through the post again but it also fails with the same error. The executable has not changed since 2002 so we know that is not the issue. Also, per our IT department, the hardware has not been touched since then. They also supposedly moved the executable to a a similar Unix box and they are getting the same error on that box. If we are running the same file using the same executable on the same hardware, why would it stop working all of the sudden? To make things worse, we no longer have the source for this post processor due to a company buyout. Our IT department said they checked the disk space on the box and that their is plenty of room. Without the source, it would take several months to recreate this post to run on a different system. I'm still thinking it has to be the hardware. As a test, we created a real small file to post and we were able to get it to work which again leads me to believe its a hardware memory issue. Does anyone have any ideas on what we should try next? Any help with this would be greatly appreciated.
