    SubjectRe: kswapd 2.4.2? ext3
    -----BEGIN PGP SIGNED MESSAGE-----
    Hash: SHA1

    Same, here. 2.4.20-xfs and 2.4.21 (vanilla) both have some problem in kswapd.
    This happened after about 4 days and 6 hours of uptime/load. I use this box
    as a router with DHCP, DNS, NTP and SSH (for administration only.)

    P100, 10GB HDD (ext3), 32MB RAM

    I noticed the two oopses in syslog - see attachment.

    Jeff.
