RHEL 6.5 machine keeps auto rebooting


Hello - I have an HP DL180 that I just upgraded to RHEL 6.5 (from RHEL 5.8). Since the upgrade, it is now rebooting automatically at various times during the day. I thought it was like something to do with the power mgr, but it is turned off... I am looking through /var/log files and such for clues but am getting nowhere.
Here is an example of what last shows:

reboot system boot 2.6.32-431.el6.x Tue Mar 31 17:22 - 19:45 (02:23)

What is going on? Evil computer?

What do you see in the logs? Nothing relevant? Do you have any agent running on this system which could cause this? Did you check iLO logs and see if anything is in there? Could be a hardware issue and coincidently it happened after you upgraded to RHEL 6.5.

Also, did you contact Red Hat about this?

I would suggest checking iLO logs yourself and log a call with Red Hat. If they (Red Hat) suspect it to be a hardware issue then log a call with HP.

if you do not have a cron job running or some other script, that is typically a hardware issue. id check the PSU first.

seeing as there is NO "upgrade" ( one that is supported by the redhat service contract) between Major versions

this is a NEW fresh clean install of rhel6.6 ( 6.6 is the current in the 6 series)

did you run the First update
or
did you have the install dvd auto up[date at time of install

Quote:

random ?

or during heavy load ?

how old is this "HP DL180"
a g9 or 6 or ??? what


have you checked the ram ?
what did memtest tell you ?

I don't see anything relevant in the logs. One log had the boot scroll in it... What I want is a log like in Solaris that shows like "CPU PANIC..." or Memory error... actually pointing to the problem or such. I have another DL380 I loaded RHEL6.5 on before this one, and it is working fine. On contacting Redhat, I try to avoid that as I don't like their support, also, they always ask for an sosreport which I cannot provide since this system is in a closed area, isolated LAN. If I make no headway here in the forum I will though. Thanks. I am still new to RHEL - how do I check the ilo logs?

Yes, random reboots. No load on it.

In case of sudden reboot and if it not from the software end you will hardly find anything in system logs. Yes, Red Hat will ask you for sosreport, they might even ask you to configure the system for coredump to catch if the crash happened due to software. iLO (Integrated Lights Out) is a HP utility which you can use to take remote of the system even when the OS is not booted. You can do lot of stuff from iLO remotely. System should have iLO card configured. This is something your system administrator can tell you. If you are the system administrator then you should find out that information. iLO logs should have information on sudden reboots and should be able to let you know why the system is rebooting.

Basically John VV is suggesting you to perform hardware diagnostic on this machine which includes RAM test.
