No core dump generated

Hi Gurus,

I'm facing the following problem. One of our applications keeps crashing with the following error: /usr/sap/NMD/MDM/bin/mds[34]: 17320 Memory fault

However, no core dump is generated. In order to analyze this issue, we need a core dump.
We have set ulimit -c unlimited, but still no dump is generated. Is there some setting in HP-UX that could cause no dump is generated?

We are running HP-UX 11.11

Regards,
Mark

Re: No core dump generated

There are a bunch of rules about setuid apps can't get corefiles. See core(4).

And of course if there is a directory called core in the current directory.

Re: No core dump generated

I don't believe you can choose wether a core is generated or not. Some problems do cores, other not. In fact, I feel like core dump comes with segmentation fault, not with Memory fault.

Anyway, if it's a program you are coding, you should try a debugging solution.

Regards,

Fred

This maybe true in some cases. If you have a signal handler, you won't get a core. But if you got the shell message "Memory fault", that's not the case. There is a security barrier that is preventing the core file.

This is still a good idea, if you own that executable and not SAP.

You could always attach to mds and if it does get a signal, you're in like Flint.

Guys,

Thanks for the replies. Apparently the system just core dumped correctly.
