PermGen space is where Sun's VM keeps class bytes. It's not garbage
collected, so if you keep adding classes to a running VM you will
eventally run out. We can only deploy a couple of times on our non-
clojure webapp, in Jboss + Tomcat. It's not unique to Clojure, but
it's true that generating classes on the fly can burn up permGen space
faster. Try increasng your PermGen space as a workaround. This arg
your jvm:
-XX:MaxPermGen=128m or so might help.
