Finally, what's especially strange is that I had gone a very long time running this exact version of Python, libraries, and application quite frequently: it suddenly started cropping up a little while ago (maybe a few weeks).

Do you mean it's a hand-compiled Python? Are you sure you didn't recompile it / update to a later version recently?

If you didn't change anything, this may be something unrelated to Python, such as a hardware problem.

You are right that ma_fill == ma_used should, AFAIK, never happen. Perhaps you could add conditional debug statements when that condition happens, to know where it comes from.

Furthermore, if this is a hand-compiled Python, you could reconfigure it --with-pydebug, so as to enable more assertions in the interpreter core (this will make it quite a bit slower too :-)).

Antoine.
