> are involved.I think this is crucial point. Not "multiple modules" (as you wrote in the subject), but "multiple processes". If each of multiple processes wants to rotate the logfile itself, it is very likely that they will work at cross-purposes. Somebody already suggested using logrotate (or similar external tools). You can then use WatchedFileHandler (https://docs.python.org/3/library/logging.handlers.html#watchedfilehandler) to automatically detect when a logile has been rotated. Alternatively you can use a central logging service (like syslog) which handles all that stuff. hp -- _ | Peter J.
