Dynamically, only because it's not otherwise specified in the options when starting up the JVM. You can edit the script it calls (check the /etc/init.d/cloud-usage script for the actual name) and add in some -Xmx 1024mb or something and see how that works.
Could also be a ulimit rather than an actual memory allocation issue. Check that the user running the service can allocate enough resources to the jvm (virtual, open files, etc) so it can create enough threads. The error you posted seems like it dies off pretty quickly but that it can at least start the JVM up, so checking ulimits shed some light. hth.
