App server shutdown

Question

Hi,
I'm trying to find out the root cause of the unplanned application server shutdown that happened in our production system.  I was browsing through the dev_w* and dev_disp files and found nothing unusual except for the log below, which I found in dev_disp.old file:
<b>Mon Oct 29 01:56:03 2007
DpSigInt: caught signal 2</b>
This was the last log when the app server shut itself down.  Can anyone tell me what the above log means?  And which other logs or trace files can I look for to help me find the root cause? 
Thanks in advance.
Best regards,
Kris Caldoza

Thanks Markus.
Below are the only logs I found in dev_disp (aside from the Signal 2 log) which were generated at the time of the shutdown:
Mon Oct 29 01:56:06 2007
***LOG Q0M=> DpMsDetach, ms_detach () [dpxxdisp.c   8415]
MBUF state OFF
MBUF component DOWN
Mon Oct 29 01:56:07 2007
ERROR => DpRqIQRemove: ShmDelete [dpxxqueu.c   430]
Mon Oct 29 01:56:08 2007
***LOG Q05=> DpHalt, DPStop ( 29771) [dpxxdisp.c   7280]
I believe it was a normal shutdown, don't you think?
