Re: kswapd (?!) error

[Petre Bandac <g38@rdsbv.ro>]

petre@k:~$ uname -a
Linux k 2.4.18-HTB #4 Wed Sep 25 02:47:50 EEST 2002 i686 unknown

it is a Slackware 8.1 installed a few weeks ago

I have 256 MB RAM and 200 MB swap space

I stay away for the experimental kernels, as what I want from my system is 
stability.

the uptime of the machine was at that time 4 days, 21:14:36. It is my home 
box, I run x-window on it (KDE), but at that time x-window wasn't running, so 
the only processes runing were those required by the system, plus apache plus 
http (below I'll list them). The only reason which comes to my mind is that 
at the time the crash occured I was doing a ftp upload on the machine @ ~200 
KB (yes, kilo Bytes). If it makes any difference, I'm connected through a 
LanCity cable modem.

I shall look at the file you mentioned, richard, thank you, though I would 
like to have some opinions on what caused this error (one of the few "fatal" 
errors I have seen on linux machines yet).
