Error Intermitent System Reboot's
Hi all,

Just started holidays (ya!) and Murphy's Law has kicked in already (doh!).

I'm looking after (when at work) two SCO 5.0.5 Systems running on Netfinity 5500 Servers (Model # 8662-3RY). Every once and a while the production server just reboot's itself. There is no mention of a cause in the system/debug/message/error logs and I'm now looking for alternative sources of information that might be a cause.

Does anyone have any ideas / suggestions as to where I might look or have seen an incident similar in your own travels?

Once i heard the story about the cleaner who pulled out the power cord, he needed the outlet for his vacuumcleaner

I've heard that story too. Another is that the cleaner plugged his equipment into a power strip and overloaded it causing a row of servers to go down.

As far as the real problem here - not much you can do. If there is nothing in ANY of the error logs, you could always call in hardware support to run test (and yes, I know this is production). Probably your best bet is to take a full backup of the server, buy/steal/borrow the exact type of equipment, build a duplicate and see if the problem shows up on it. If so, software or something running at the same time causes the crash. If not, hardware on the original - but good luck figuring it out until it either sends a message or fails completely (usually memory is a culprit in those situations).

Guys,

Found this in the /var/adm/syslog (must have been looking in on planet Mars the first time). The following is an extract of the syslog that is generated from a script that checks the log every evening at 23:55.
Code:

What's this Licensing Policy Manager Daemon (ifor_pmd) ??

This should not cause a reboot.

Do you have more information about the reboots?
e.g. like alway at the same day/time, or always when a specific job is running?

when this happens mostly it had to do with the power or rear hardware problems, because otherwise the systems logs the reason of this PANIC reboot.

One of your errors is posted at PCUnix.com SCO FAQ ( ifor_pmd failed to init)

It is not out of the realm of possibility that you have a hardware problem.

I have systems that will panic and reboot when they have a hardware failure with a CPU or a card or even with memory. I would suggest that you have your hardware looked at.

If you have any crash dumps I would look at those, if your system has such a thing.
