Untraceable Reboots

[BFA6]

Hi,

Is there anything in /var/tombstones? Have a look at timestamp on ts99

Regards,

Hilary

Also do check any single line message in the OLDsyslog.log as "memory full".

When the RAM is full with no swap space,might trigger a similar condition.

Hi,

I'd suggest you run check_patches to get a more comprehensive check of your patching situation. Make sure that you have PHCO_22044 or a newer check_patches patch first though!

I did notice that one of your patches (PHSS_20146) is actually a workstation firmware patch - which makes me wonder how the other patches have been applied...

regards,

Darren.

Hi Ralph,
did you capture anything interesting from dmesg before the server hit the ground? If the server does this often, you could try to setup a cronjob for writing the output of dmesg to a file. Perhaps something interesting would appear.

regards,
John K.

well I would think that you have had eihter:
A power failure or
Someone issueing the reboot -q command or a Hardware failure in something like a system board or power supply.
Get htese checked out if I were you.

Hilary,

as I wrote, ts99 got a recent timestamp which corresponds to when the machine ran the rc scripts

# ll -rt /var/tombstones/
total 84
-rw-r--r-- 1 root root 6864 Aug 29 2002 ts94
-rw-r--r-- 1 root root 6864 Sep 15 2002 ts95

T.G. M.,

no there are no occurrances of /memory/i in OLDsyslog.log

Darren,

thanks for the advice to run check_patches.
The logfile it created gives me sufficient hints to follow first

# check_patches -imops
Obtaining information on installed patches
Checking for invalid patches

Melvyn,

this box is no longer under HW maintenance contract, but I will check if I can find myself sufficient evidence that power supply is ok.
