I patched my RHEL 4 ES server and now I am getting segfault errors.


I recently patched two RHEL 4 ES servers and since the reboot both servers are now reporting segfault errors:

Server - Proliant BL25p
emdctl[19053]: segfault at 0000000000000078 rip 00000000f7033f2e rsp 00000000f66d02e8 error 4

Server - VMware
tnslsnr[8177]: segfault at 000000000000000a rip 0000002a96dd5878 rsp 00000000409ffef0 error 4

I can't find any info on google specific to these errors. How do I troubleshoot these types of errors?

TIA!

Since they're RHEL servers, I'd send the dump files to RedHat, and open a support call.

When does the segfault occur, boot time, while applications are running or starting, etc? What specific patches did you update or apply? Both of those you displayed with segfaults seem to be related to Oracle.

Both servers are Oracle servers. The patching was 'up2date -uf' and then a reboot. I didn't notice the error after I rebooted. I found the errors when I was checking the servers (dmesg) for errors (a process I run every morning).

Despite what dmesg claims, do both of these run or are running without issues? Any other problems or anything out of the ordinary? If working or not, probably wise to submit the info to Oracle with the patches you applied and or Red Hat. I'm guessing since they're both related to Oracle, Red Hat isn't gonna care as much.

I'm waiting to hear from the Oracle DBAs.

Thanks for all the feedback and info.
