[rules-users] PermGen space error

There are several different memory settings, but the "Perm Gen" is related to
this one:  MaxPermSize

These are related to the heap (the normal memory space that we are used to)
-Xms128m            This sets the initial size of the heap
-Xmx1488m           This sets the maximum size of the heap

These are related to the perm gen space (typically used for holding class
defs, etc...)
-XX:PermSize=32m          Similar to the Xms, this is the initial size of
the space
-XX:MaxPermSize=200m    Similar to Xmx, this is the maximum size of the
space

The perm gen space doesn't need to be nearly as big as the heap.

Hope this helps.
