You should upgrade to PyPy 4.0.1.  (Generally speaking you should always run the latest available PyPy, since they only really do bugfix and performance releases; they don't break compatibility)  I don't remember what version it was in, but somewhere in the 2.x series there was a nasty file descriptor leak whose symptoms might match what you're seeing.
