Number of loaded classes in Java heap : 11,862 
Number of classloaders in Java heap : 84 

NOTE: Only for Java 5.0 Service Refresh 4 (build date:February 1st, 2007) and older. When you use delegated class loaders, the JVM can create a large number of ClassLoader objects. On IBM Java 5.0 Service Refresh 4 and older, the number of class loaders that are permitted is limited to 8192 by default and an OutOfMemoryError exception is thrown when this limit is exceeded. Use the -Xmxcl parameter to increase the number of class loaders allowed to avoid this problem, for example to 25000, by setting -Xmxcl25000, until the problem is resolved.  Please examine the current thread stack trace to check whether a class loader is being loaded if there is an OutOfMemoryError. For example, the following stack trace indicates that a class loader is being loaded:  at com/ibm/oti/vm/VM.initializeClassLoader(Native Method) at java/lang/ClassLoader. (ClassLoader.java:120)
