I just had a strange case where kswapd started eating up 100% CPU time. I haven't been able to reproduce it, but it seemed to occur when I did a "dd bs=4096 </dev/fb0 >/scratch/image" in X while writing a CD (4x) from the same filesystem--the dd took 10-20 times longer than usual, and kswapd's run time from ps also pointed to the same time. At the time, roughly 6MB of real memory was free, but most in-use memory (~800MB) was cached data; only 3MB or so of swap was used. The system itself seemed to remain stable, though I rebooted shortly after I discovered the problem.
System is as follows: (if more info is desired, please contact me directly at achurch@achurch.org--I'm not subscribed to the list)
Kernel: 2.4.13 (i686, SMP) CPU : Dual Pentium II 400MHz Memory: 896MB RAM, 576MB swap IDE : 1 HD (data, including /scratch, and 512MB swap) SCSI : 1 HD (root and 64MB swap), 1 CD-R drive Video : 3dfx Voodoo 3 (PCI), 16MB VRAM (3dfx framebuffer driver enabled for virtual consoles, but X hits the hardware directly)
