We have a user where a process is behaving abnormally and crashing. It would be great if a core file was generated, but I don't see one.
There is no core file being created in the /opt/core directory. Now, I have asked the user to submit the output of errpt -a and to check for errors with the following: LABEL: CORE_DUMP_FAILED.
There were none, unfortunately.
The user does not have root access to the AIX box, which means they cannot modify the location where core files are being generated, which I don't think would matter.
My question is whether having root access could be responsible for the core files not being generated or could it be some other cause?

Reason: Add missing CODE and ICODE tags.
No, the user does not have write permissions to /opt/core, but only read and execute.
However, we are expecting the core dump to appear in the working directory of the process which is crashing. The user does have write permission to this directory.
I decided to collect some permission data:
The output of errpt -a is as follows, which does not display any Core Dump related failures.
Since the failing process is in a directory with the path /apps/ptadm2/tower/vidm/home/runtime/is/, I assume this is where the core dump would be. The output of the lscore -d is what confuses me. I am unsure which directory the file should appear in -- however due to output of errpt -a, I am unsure whether the system is attempting to generate the core file at all.

The literal error message is "File System Full", and the filesystem to focus on is:
Maybe the message is wrong (FileSystem Full) - but I would check.
In any case, I would consider making /opt/core a separate filesystem rather than piggyback on /opt.
Hope this helps!

Hi,
Currently, we have a Perl script from a third-party vendor that is generating core dumps. It has been reported. We can't turn off the script as it does generate some diagnostic file that's required. So at the moment, we have to let it continue to do its run.
I wish I can say the vendor is... (8 Replies)
