Instantly restart a server or workstation each day
Authored by: patpro on Oct 17, '05 10:21:27AM

if you are using a hand-made IPFW ruleset, you might want to check that you are not using keep-state rules on dual processor Mac. There is a nasty bug in the kernel/IPFW implementation that will make your machine freeze with that setting. (bug #4112652 on Apple's bugreport, flaged as closed, should be fixed in 10.4.3)

That's interesting because I do have a hand-made IPFW2 ruleset. However, my boxes are single processor machines.

Is there any word on this bug affecting G3 towers (all G3 towers were single processor)?

nop, single proc system are not affected. In fact, on a dual-proc system, if you disable one proc by using "Processor" system pref pane, you avoid completely the problem.

Interesting to note, thanks. I'll post that comment on Apple's board as it may help someone else. Though in my case all my servers are behind SonicWalls so no help, but still every thought is appreciated.

that's a shame, back in May-to-August there was a full thread (at least 50 posts, maybe around 80) about this issue. Too bad Apple deleted it.
