We have a network of 7 FreeBSD machines here. KILROY is currently our
main file server. All of the machines, except for one (Hades), are
running FreeBSD 1.1.5.1 w/patches. We would like to upgrade all of our
machines to FreeBSD 2.0.5, but we have to make sure it's stable first,
and it doesn't seem to be quite there yet.
Not quite sure how to track this one down, but I've got three major problems
with the 2.0.5-RELEASE so far.
1) I keep getting "nfs send error 65 for server kilroy:/home" errors. At
first this doesn't seem to be a problem, but after a few of these errors
the entire FreeBSD box "locks up". I'm not sure if these two are related,
but thought I would mention it. By "lock up", I mean the console & telnet
ports lock, but it looks as though the system is still running (Ie: screen
saver is still going).
2) I have a MUD (LP-Mud Game Driver) that is ran on the 2.0.5 machine. It
dies rather often under 2.0.5-RELEASE with SIGFAULT or IOT Trap errors.
This same game, on the same machine, running 1.1.5.1 w/patches would
run for 15-20 days before upgrading to 2.0.5, now it runs anywhere from
a couple minutes to 4 hours.
3) The 2.0.5 machine keeps rebooting about once every 24 hours or so. I
haven't checked the logs before to find out why, but this time I did
and found:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x2a
fault code = supervisor read, page not present
instruction pointer = 0x8:0xf0108c8d
code segment = base 0x0, limit 0xfffff, type 0x1b
