I have 512 MB for the initial memory pool and 1024 for the max. I believe
that this is less than what is recommended, but I've had some issues with
Tomcat not being able to start because the JVM can't find enough contiguous
memory space, so I don't think I'll be able to increase it until we deploy
IdP v3 to production.

Sounds good. Of course you'll want to keep your eye on the logs in case it
happens again (which is likely).

May I ask how much heap you have allocated to the JVM?
