I have this machine set up as a Postfix/Spamassassin mail relay server for our LAN (125 users). When it works, it kicks serious *ss. The problem is it crashes (completely) every couple of days under load. The error message in /var/log/messages reads
[Kernel] Unable to handle page request.
and then a whole bunch of gibberish.
The machine specs are as follows
p-II 266, 256mb ram, 10Gb hdd, two nics (one 3com, one lynksys isa), and a slim installation of Redhat 9 running only Postfix, Spamassassin, and Iptables as services.
Is this indicative of a memory issue? Or is the machine just too old to serve in this capacity?
