Hi Carlos,

try using weak references for internal tables, e.g. in the registry
file:

# List of choices for internal tables impl (PyJavaClasses canonical map
etc.),
# these are separated through ':' and tryed from left to right.
# For long running applications under java2, needing classes unloading,
# in order to have jython runtime automatically discarding 
# no longer needed info and avoding memory leakage, this can be set 
# to weak or soft (=> an impl. using weak-refs or soft-refs will be
used).
#python.options.internalTablesImpl = soft
python.options.internalTablesImpl = weak

In my case, weak solved a memory leak, while soft was no help.

Best wishes,
Oti.
