[jj1985]

Perm generation refers to the heap space where all the loades classes are stored. It's exclusively used to store the class definitions. Guess your applications has very huge number of classes.

You can increase the PermSize :
java -XX:MaxPermSize=128M <application>

Try incrementing the permsize by trail and error

To set a new initial size on Sun JVM use the -XX:PermSize=64m option when starting the virtual machine. To set the maximum permanent generation size use -XX:MaxPermSize=128m
option. If you set the initial size and maximum size to equal values
you may be able to avoid some full garbage collections that may occur
if/when the permanent generation needs to be resized. The default
values differ from among different versions but for Sun JVMs upper
limit is typically 64MB.


Some of the default values for Sun JVMs are listed below.

JDK 1.3.1_06  Initial Size  Maximum Size
Client JVM  1MB  32MB
Server JVM  1MB  64MB



JDK 1.4.1_01  Initial Size  Maximum Size
Client JVM  4MB  64MB
Server JVM  4MB  64MB


JDK 1.4.2  Initial Size  Maximum Size
Client JVM  4MB  64MB
Server JVM  16MB  64MB


JDK 1.5.0  Initial Size  Maximum Size
Client JVM  8MB  64MB
Server JVM  16MB  64MB
