Recently installed 3.1-R on an Apricot Shogun server. Some sort of
biggish Intel Motherboard with a single Pentium 133MHz on a single
CPU board.
The machine is setup as a news server running inn-2.2. I've got our
current news server feeding this box as a test. Ran fine for a few days,
but now panics everynight, during expire, judging by the time. I'm no
expert with working out why it's dumping so would appreciate some help.
The hardware previously ran for a couple of years with NT 3.51 with no
apparent problems. This is (was?) to be our first production FreeBSD
box if the test went well.. We plan to move all operations over to
FBSD; news, qmail, web cache, etc., but management aren't impressed
by this sort of thing :(
