Segfault error at 4

[Chui Kock You_1]

Hi,

We got problem with HP DL785 server. Almost every day the server reboot (refer attachment below).

Recently i am getting alerts in in message log for segfaults error 4...

What could be the problem and any solution for this..

Can anyone give me why this error occurs and what is it's meaning.

I am running Red Hat 5.4 on 64bit Proliant server.

Your help is highly appreciate.

Regards
Chui

The segfault message indicates a program named "cdr_filter" is repeatedly crashing with a "Segmentation fault" error.

"segfault at 000 000 00 000 00 000" indicates the program is trying to use an uninitialized pointer, which indicates a bug in the program.

(In programmer-speak: "cdr_filter" is trying to dereference a NULL pointer.)

This should never cause the server to crash & reboot. Reporting application crashes to syslog is a new RedHat feature: traditionally, segfault messages are displayed only to the user running the program.

Please run "hplog -v". If you have the hp-health RPM installed, this command should display the hardware log (IML = Integrated Management Log).
