Bug#2692: kernel swap space problem

My machine, which has been running linux 1.2.13 and afs-1.2.13-21
smoothly for months, is showing some strange symptoms. On several
mondays, it has all but refused to accept TCP connections. I persisted
in trying, and discovered that it was accepting them, but very slowly.

I logged in to discover that there were zillions of cron processes
taking all the CPU and memory.

I'm not even sure if cron has anything to do with the problem.

I'm writing today about something I found in the logs:

The only thing I can think to suspect is AFS.

Linux-afs folks: have you seen these swap-space bad map messages?

Does anybody know why my computer thinks lp1 is out of paper?

I installed the debian image, but I'm actually running a kernel
that I built myself. Nothin fancy: just the usual make config and make.

Here's the status of the debian image package, in case it's useful:

connolly@beach ../boot[587] dpkg -s image
