occasional core dump

Hi,

We have one application (c language) installed on our AIX 5.2. When we enter some large amount of data in one screen and do update, it is dumping core some times without any error (like bus error, segmentation fault). Next we open the application again and enter the same data and do update. This time updates go through fine without any problem.

This problem (core dump) is happening only with that particular screen and occasionally, not always for the same data update.

We tried the same on another machine. It is not dumping core on that. Updates are going through fine always.

What can be the cause for this problem? Is this problem due to some memory settings? How to troubleshoot this problem?

Please let me know, if you need more info.

Please help ...

Thanks,
Venkat.

NAME
abrt-action-generate-core-backtrace - Generates coredump-level backtrace SYNOPSIS
abrt-action-generate-core-backtrace [-v] [-r] [-d DIR] DESCRIPTION
This tool uses coredump from the file coredump and binary at the path stored in file executable in the problem directory to generate coredump-level backtrace. Coredump-level backtrace resembles ordinary backtrace in that it contains information about call frames present on the stack at the time of the crash. However, it only contains information that can be obtained from the coredump without debugging symbols available - mainly relative addresses of the stored instruction pointers. Such backtrace can still be useful for reporting and reproducing the bug and does not require debugging information files to be installed. The result is saved in the problem directory in a file named core_backtrace. Integration with libreport events abrt-action-generate-core-backtrace can be used as an analyzer for application crashes which dump core. Example usage in report_event.conf: EVENT=analyze analyzer=CCpp abrt-action-generate-core-backtrace OPTIONS
-d DIR Path to problem directory. -r Do not hash function fingerprints. Useful for debugging. -v Be more verbose. Can be given multiple times. AUTHORS
