Yes.

Try to set user limit of core to unlimited as,

# ulimit -HSc unlimited

# file core
# what core

You can use gdb / adb to debug problem with application binary.

There is document that gives required information. The things to check are as follows.

1. /etc/shutdownlog
2. ts99 file in /var/tombstone directory-particularly for hardware related crash dumps.
3. There is crashinfo tool utility
4. adb -m /var/adm/crash/crash.0/vmunix /var/adm/crash/crash.0
Once on adb prompt, do
msgbuf+8/s

If you have contract with HP, HP will do it for you.

5. Q4 crash dump analysis.

Use HP's WDB to analyse core files generated by any application. To analyse crash( kernel) you can use Q4. All crash dumps will be at /var/adm/crash
