Greetings. I have some trouble brewing. This machine, a 386 running SCO Xenix 2.3.2, has recently run into a deeply wierd problem. The system has been up and running flawlessly for about 2.5 years now, with the occasional rebuild of the filesytems to avoid fragmentation. The machine is only used as our news machine (since nobody likes being on a machine grinding away on rnews...). No new hardware or software changes have taken place (except adding a few more uucp connections) The problem: The system just stops. The Disc light comes on, but there is no movement on the disk drive. One can hit the ALT-Fn, to switch between virtual screens, one can type and see the typing echoed, but as soon as it tries to execute anything (even a login), the process hangs. This is merely annoying right now, since I have to reboot at the office, and it typically goes down at about 3:00 am (actually there is no pattern to when it goes down - I find nothing in crontabs, nothing in the uucp .Logs, nothing regularly occuring at crash time). Today it hung with no activity other then two rn sessions (ie no rnews, uucico, etc - so the process table couldn't have been full) I'd really like to solve this soon, before anything major happens. I'm sure my downstream sites are getting a little annoyed at the problem. I've run a full non-destructive verify of the disk, and fsck more times then I can remember, plus several cpios to tape just in case. Any ideas, hints, etc?

In general, it's much easier to diagnose such problems if a full hardware list is included, along with your version of Xenix and any supplements you've added. In this case, the particular controller you're using is going to have some impact on the answer. For instance, if you've got a WD1007A we'll ask whether you've installed sls133. If not, that's probably your fix. -Richard

It sounds like your disk controller may be going out to lunch on you. A considerably more remote possiblity would be that you are experiencing the effects of ``chip creep'' if your temperature variance is high.
