hi

try increasing the JVM heap size -- set to 256mb, or 512. That should be plenty. As per http://www.informix-zone.com/node/46

e.g. when starting tomcat:
export CATALINA_OPTS="-Xmx512m"
$CATALINA_HOME/bin/startup.sh

not sure why this is required in your case but i've seen other memory-hungry j2ee apps fail on tomcat with the same error.

note: i don't think subsonic is memory-hungry, but maybe it is if you have a huge library. shrug. good luck!

i spoke too soon

check the subsonic war deployment requirements - it clearly states it requires a container that supports 2.4 servlets (as per http://subsonic.sourceforge.net/installation.php)

if you look at the tomcat homepage, you see that starting with 5.5.27 it supports that:
2.4/2.0 5.5.27
(as per http://tomcat.apache.org/

so that is probably why it's not working on an older version of tomcat.

peace out
