App server shutdown

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

    consider upgrading your SAP kernel.

    also check if anybody kill processes at OS level or in SM51/SM50

    • you must have some kind of OS script to shutdown SAP. check in every user`s shell history to see if it was used recently.

      also check backup scripts, reboot scripts. anything that uses stopsap.

      check crontab, check "at", check external schedulers.

    Signal 2 is SIGUSR and is send if you e. g. increase the loglevel of a specific workprocess (e. g. using SM50).

    In dev_disp you should see, why the server was shut down (normal shutdown, crash) etc.

      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?

        Hi,

        Is there any info in sm21 log?

        Is there anything in the OS system log ? ( 'errpt -a | more' at unix level if you are on AIX.)

        KR,

          Thanks Alluni.

          I did not find anything "unusual" in SM21 when the shutdown happened.

          The app server is running in HP-UX, which logs should I check at the OS?
