From this forum post[1] you should just be able to modify the catalina startup script,

Gotta go out so I don't have time to try it myself, but good luck!

I've managed to increase the memory by adding:

export CATALINA_OPTS="-XmX2048 -Xms2048"

to /etc/init.d/tomcat. However, it hasn't fixed my deployment problem:

deploy-webapp:

And now I look at the stack trace a bit closer, I wonder if it's Ant that's running out of space.

It was Ant by the look of things. In the end I added:

ANT_OPTS="-Xmx1024m -Xms1024m" export ANT_OPTS

to /usr/share/ant/bin/ant and it appears to have fixed the problem.
