The problem would have bitten me by now. I'd say the patch has fixed it.
Thanks for all your work Don. Good stuff!
Cheers,

I'm only seeing this problem on only one of my systems, the firewall, which
has the smallest memory configuration (48 MB). The problem doesn't occur
immediately after reboot but does occur a few minutes later when the squid
proxy finally comes up.
So far I'm seeing an uptime of:
4:45AM up 8 mins, 1 user, load averages: 0.07, 0.64, 0.46
I'll watch it for the rest of the day.
Interestingly the other four systems running -CURRENT, three here at home
and my desktop UNIX system at work (sorry, my prod systems at work still
run -STABLE) have not exhibited any symptoms.
As far as any other symptoms are concerned, it never stayed up long enough
for me to notice any other symptoms. What prompted me to notice is that my
Internet connectivity disappeared because my firewall was down. As I hardly
log into the box (it normally just... happily runs), I never really noticed
anything else. I only log into it to maintain it, the rest of it's pretty
much automated. So, no, I didn't notice any other symptoms as it just
stopped working after the upgrade.
I will let you know by tonight how it fares. So far so good and this is a
good sign so far.
Cheers,
