[2.] Full description of the problem/report: An old 486/66 with 20 Meg memory runs a a firewall at home. Probably runs too much for that amount of memory (sendmail, bind, ntpd and FreeSWAN VPN), but I can't find any more memory modules! I have gotten four or five oops the last week or so (in different processes), running 2.2.18. Stepped up to 2.2.19pre7 and hooked up a serial console two days ago, now I got one again.
