Hope you all had a good one. I need advice on debugging kswapd oops. I get these on every kernel from 2.6.5 -> 2.6.9. 2.6.4 performs OK. I am currently building 2.6.10 to try this as I see in changelog there was some work done in this area. The oops is always kswapd writing to and unpaged area (I believe). I have tried everything... 2.6.4 just works. 2.6.5 -> 2.6.9 can run anywhere from 7 to 90 days before I get an oops. After an oops the system stays up, but I cannot login on any terminal and new connections (pop3 etc.) fail. I can't really give much info, as it all varies, but I really need to sort myself so I _can_ give you all correct information. This is also my gateway, so I cannot play around much on this box. I have new memory coming, so that will also aid to debugging - current memory is 128MB with 128MB disc swap and 260MB file swap: total used free shared buffers cached Mem: 126872 123032 3840 0 19088 49956 -/+ buffers/cache: 53988 72884 Swap: 398648 1452 397196 The box runs httpd, ntpd, ssh, nfs client, sendmail, spamd, ircd, pop3, iptables/NAT, DNS cache server.

Any help on what to do to trap this properly much appreciated. Thanks, Nick -- "When you're chewing on life's gristle, Don't grumble, Give a whistle..."
