Thoughts on how I might overcome this issue so I can see if using
pypy3 over CPython 3 garners better performance for my specific
application?

Without seeing your code it is difficult to be specific. Typically this
is caused by not closing allocated resources. CPython uses reference
counting, and so it implicitly releases resources when they go out of
scope. PyPy does not. Are you calling socket.close() or fid.close() when
you are done with them? Also see this section of our documentation
