User Comments:
vamiot: running a program under jython (works fine with regular Python 2.6.1 64bit), parses a large text file (3 Million lines), generates some 20K xml records
Jython a 32bit version?

Thank you for your report. 

You probably need to increase the heap space allocated for Jython. 
    
Jython has its own -Xmx (maximum memory heap size) setting which you can find in jython.bat in the bin directory. Currently, this setting defaults to -Xmx512m, but you must set it to a sufficient size to run YOUR app, otherwise you will get Java OutOfMemory exceptions (even when there is plenty of spare memory on your system).

I tested adjusting this setting and it worksforme. 

If that's not the issue, then feel free to reopen with my apologies.
