Test started: ~90MB at run time.

It seems that the audio output is not being initialized and closed correctly. Perhaps it is not drained and fully closed at the end of a pass? This seems to get worse after multiple passes. Could this be the memory leak?

ac2cz commented 8 years ago

The audio issue is fixed in 1.03a. Need to run overnight to see if it fixes the memory leak

ac2cz commented 8 years ago

This seems to now be more stable.
