hi,
i use pypy 2.6 with BeautifulSoup module and pymongo. i make a spider with the pypy.
when i run pypy ,i found a problem ,the pypy use memory higher then 6GB
when i run pypy at once , the pypy use only 240mb memory!
the screenshot in the attachment!

This might be because of the differences in memory management.

Unlike CPython, PyPy does not free resources as soon as the last reference to an object goes away. See

http://pypy.readthedocs.org/en/latest/cpython_differences.html#differences-related-to-garbage-collection-strategies

The solution is often to close resources explicitly or use "with" blocks.
