Reading a core file

Eric Willson — Thu, 17 Oct 2002 14:07:45 GMT

Our system dumped a core file out on root this morning. I swerved into "gdb" and it tells me the core file was generate by "smdb" and "Program terminated by signal 6, aborted". I looked for a process called smdb and found nothing. I searched the knowledge base for smdb and found nothing. Can someone help me figure out why this core file was dumped?

Hello,

Do an ll on the core file.

Are there any cron jobs at that time?

How about the correspding timestamps in /var/adm/messages and/or /var/adm/syslog? Do they report anything out of the ordinary?

What applications do you have on the server? It could be an application-secific process.

Hope this helps
Chris

Hi

smdb (Strong motion data base) ?

A sig 6 aborted I would guess that it was uswer aborted.

Hi Eric,

If you typo'd that cause it was actually smbd that would be the Samba (NFS to/from PC) daemon.
And signal 6 is indeed Process abort & could have come from a number of sources including a user doing a ctrl-C or a condition which caused the process to abort.

Check to see if you have Samba installed on this system.

Rgds,
Jeff

If you have samba on the machine it should be the "smbd" not smdb daemon which has dumped the core.
check it up.

The smbd willalso be rinning if you have CIFS installed (it's buildt on Samba).

I did enter a type and yes, it is from Samba. Apologies to Paula, who took me at my word and correctly identified smdb, for the low number of points.
