Hello!

I got this on my masq box:

Is this hazardous? The machine is still up and running.

uptime is around 43 days and squid has been running more than half of that
time. This machine is a 386DX40 with 8MB memory and 25MB of swap -- but
hey, i got it for free :) -- featuring 3c509 and an internal modem for
ppp connection (yes, it was up at the time of the fault).

squid is acting funny, even though i restarted it. I was about to shutdown
the machine anyways, because of a hardware "upgrade", now it seems I'll
compile a new kernel for it, too. Is this a known problem fixed in
2.0.34-pre8? I don't think 2.1.x will do any good to that box :) And i'd
rather not have others in the household complain about not being able to
read mail since that box is also an imap server.

If someone's interested, i can provide more info.
