Improve logging #168

Open wschoenell opened 7 years ago

wschoenell commented 7 years ago

I am having this error when running Chimera on Windows, but it is probably an error for the other OSes. In doRollover() it sometimes complains that the file is already open by another process. This is probably due to multiple concurrent threads running in the same log file.

A solution may include changing Python's default RotatingFileHandler for the ConcurrentLogHandler alternative module.
