[jboss-user] [Installation, Configuration & DEPLOYMENT] - Hot deploy causes OutOfMemoryError: PermGen space

[basca]

After several deployments of my WAR, by copying new builds to the deploy directory of a running JBoss instance, I encounter OOMs as illustrated in the following log fragment:

18:13:56,799 ERROR [ContextLoader] Context initialization failed
  | 18:13:58,893 ERROR [[/mywar]] Exception sending context initialized event to listener instance of class MyContextListener
  | java.lang.OutOfMemoryError: PermGen space
  | 18:14:00,924 ERROR [BaseModelMBean] Exception invoking method addChild
  | java.lang.OutOfMemoryError: PermGen space
  | 18:14:01,940 ERROR [BaseModelMBean] Exception invoking method init
  | java.lang.OutOfMemoryError: PermGen space
  | 18:14:05,111 WARN  [ServiceController] Problem starting service jboss.web.deployment:war=mywar-3.0-SNAPSHOT.war,id=1629201312
  | java.lang.OutOfMemoryError: PermGen space
  | 18:14:07,143 ERROR [MainDeployer] Could not start deployment: file:/D:/JBossAS-4.0.3SP1/server/default/deploy/mywar-3.0-SNAPSHOT.war
  | java.lang.OutOfMemoryError: PermGen space

I've done some research and there seem to be several possible causes. What approach do you suggest in tracking this issue?

Environment:
11:33:16,447 INFO  [Server] Release ID: JBoss [Zion] 4.0.3SP1 (build: CVSTag=JBoss_4_0_3_SP1 date=200510231751)

Many thanks!
