I'm the author of the Pyana package and, to the best of my knowledge,
Pyana does not have any memory leaks. It seems like there are three
possibilities: your code is leaking somehow (seems unlikely based on
the above), Pyana is leaking (very possible) or Xalan is leaking (very
If Pyana is leaking then it is likely that the problem can be fairly
easily isolated and fixed (by me). Would it be possible for you to
isolate the leaking code and send it to me? If that is not possible,
then let me know and I can recommend steps to help find the problem
