kswapd and system response

hi there,

every so often, my system (2.4.13 smp) gets really sloooooow. a typical top
looks something like:

  PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND
    5 root 14 0 0 0 0 RW 99.9 0.0 7:52 kswapd
    7 root 9 0 0 0 0 SW 1.9 0.0 0:04 kupdated
 2053 root 13 0 984 984 776 R 0.7 0.4 0:01 top
 2063 p 9 0 2080 2080 1292 S 0.3 0.9 0:00 vim

kswapd is definitely not behaving correctly.

the thing that brought it on this time was gtv (an mpeg viewer which uses
sdl) bailed on me. X "kind of" froze, so i killed it. but that's only the
cause this time around. last time, it happened between the time of going to
bed and waking up (ie- the system was pretty much idling from a user's pov).

this has been happening with the 2.4.13 kernel every couple of days.

i thought i'd post it to lkml to let someone know that there's a problem.
i'm not subscribed to the list, so if there's anything else i can do to help
diagnose what's going on next time it happens, please cc me.

i feel like such a loser when i reboot. ;) i heard that 2.4.15 was just
released, so i'll try upgrading to that and see if it helps any.

pete
