I am attempting to get the Quickstart version of Grouper going. I start HSQLDB and it appears to start properly, but when I try to stop it I get an error and it doesn't stop I have to Ctrl-C to stop it. To attempt to stop it I telnet in to port 9001 and issue the SHUTDOWN SQL command, in response to that I see:

[java] Exception in thread "HSQLDB Connection @1b543c88" java.lang.OutOfMemoryError: Java heap space

So I Ctrl-C to stop it.

What do I need to do to get this to work properly? Below is everything I see when running HSQLDB. The server is a Sun 4100 with 2 dual core AMD processors and 8G of memory running Redhat AS Release 4.
