We've been experiencing memory problems here using JBoss 2.2.2 on
Sun's JDK 1.3.1 for Linux. Switching to IBM's JDK 1.3.0-8 seems to have
solved the problem though. If you're using 1.3.1, try downgrading to 1.3.0
(you can try IBM, Blackdown or Sun -- I can't seem to find 1.3.0 on the Sun
website though).
HTH.
