The box is running slink, with all packages, except the kernel and
samba, "apt-get upgrade"´d to potato. Uptime is between 30 min and 5
days, I´m running X w/ fvwm95, setiathome in the background and, when
I´m home, netscrap _may_ run. The system is IDE with a SCSI-streamer
and -CD-recorder on a ASUS P54C-mobo with 4x16 MB FP-RAM and a Matrox
Mystique as gfx card. 3 PCI-ethernet-cards, one ISA, and a SB16.
Problem is that I can´t find any similarities between the hangs, the
box can run ok for a few days, burning CDs, ripping and encoding mp3s,
looking for ETs ;-), and doing ~1k mails per day, and at 3 am
(according to my ping stats from outside) it´ll freeze. Since the
connection to the outside is via PPTP, which hangs too, I can´t reach
it anymore, although it answers to ICMP from local networks. but I
can´t even get a TCP connection open (it sends nothing back, not even
a syn_ack).
The box is running as-is now for about a year, but is ~3 years old, so
I guess it´s simply getting old. Cheap hardware isn´t built for
running a 24/7 server, I guess.
It shouldn´t get too hot, since I already underclocked it from 66/2.5 to
60/2 and I´m having 2 extra fans, one cooling the PCI and ISA cards,
one cooling RAM. Also it sometimes freezes when loaded, sometimes when
idling (I´ve disabled setiathome for testing).
But that´s not the real problem, I´ll simply get a new used PC (used
P1´s are for sale at about $ 100) when I´m back from the trip, what I
need for the time being is a solution where it would simply reboot
when having trouble, and I _guess_ the software watchdog _may_ be what
I´m looking for in this case.
