I'm not really a linux expert, so I can only be suspicious.
Masquerading of iptables 1.2.5 sudently idles when "iptables -L" shows
everything is alright. A realoading of rc.firewall brings everything back to
normal. That happened 7 days after a normal operation. I've now upgraded to
1.2.6 and see what happens.
Also, crond doesn't seem to operate very precisely. It is sometimes seems
idle for 30 minutes.
I know that these may be application-specific problems, but I was curious if
there are any current kernel issues related to them so I can quit searching
for another cure.
Thanks. Michael.

Neither am I but I after seeing strange cron-jobs being run in the
future according to the log,I upgraded to 2.4.19pre3 and all was ok
again.

I tried running this small script under 2.4.18 and noticed very strange
outputs..
// --- start ---
#!/bin/tcsh
while (1)
date
end
// --- end ---
./timescript > output
output gives me this;

Which clearly shows that something is very very strange.
I've no idea where or why this happens but since upgrading to 2.4.19pre3
helped I assume that there is something in the kernel that is wrong.
I run SuSE7.2 with a vanilla 2.4.18 (now 2.4.19pre3).

Can you try to reproduce with pre1 and pre2?

Not sure it is quite relevant but...
I had such a weird behavior on my Abit KT7 (with VIA chipsets) based
system: the time often went wild when I started doing heavy I/O between
IDE0 and IDE1... and after that the system had to be restarted :/
The workaround below by Vojtech Pavlik has fixed this issue on my system:
