Hi Kevin, I can't help you with what you're asking for, directly, but as a suggestion on something to try, if you make a small script that dumps the currently running processes into a date/time stamped text file, new for each time it runs, then you could set it up in the system scheduler to run every "x" number of minutes. You could schedule it to start running at something like 1:00am. It might help to isolate exactly what processes are running just before the lock-up and give you some more information to work with. I'm guessing that it's a process and not something like the /tmp location getting "full" for some reason.
Good luck.

Overnight, the system will just lock up and stop responding. Normally there isn't anyone doing anything at night; the backup runs, that sort of thing, but then some days when they come in early in the morning the entire machine is unresponsive. Connecting with telnet there is no login prompt, just a blank screen. It happened last night and I've confirmed from the logs that the backup (which is using a split mirror backup strategy) ran successfully and finished at 2:02am. Sometime between then and 4am, when there really should not have been anything going on, it just locked up. Are there any logs that can be enabled on AIX to record some evidence for these kinds of failures so we can figure out what's going on with this machine? -K _______________________________________________ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users _______________________________________________ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
