Info on BUS Error

Marie-Josee Cormier — Mon, 17 Nov 2008 18:32:43 GMT

Well, that's a first, after a few years in production with HP-UX 11.i.. We had this in one of our system logs..

/userdisk/prod/drd/script/scriptname.sh[28]: 13593 Bus error(coredump)

Should we be concern?

Hi,

whatever this script is intended to do, it went wrong.

/userdisk/prod/drd/script/scriptname.sh

You should first investigate what this script does - maybe

file core

can tell you where it crashed.

It depends what the script does. Take a look at line 28 in this script. It is the process in that line that coredumped. There is probably a core file either in the home directory of the executing owner of this srcipt (and/or home directory of executing owner of the proces in line 28) or in the default path where the script was invoked from. You should check the core file with the "file" command to find out the cause of the core dump. Additional troubleshooting can be done by analyzing the core file by HP or the developer of the process in line 28.
Most likely after a few yesrs in production you ran out of some resource, maybe a memory leak.

Ok, i'll take a look into this..

A weird thing, doing a find this morning generated a bus error again..

[root@myunix /bla/bla] file core
core: core file from 'find' - received SIGBUS

Weird weird right?

>core: core file from 'find' - received SIGBUS

Do you have the latest patches for find and libc?

Well, I started seeing some more, something definitly wrong on my system.

I have a core dump file, and submit it to HP for evaluation.

Thanks to all for your help!
