New submission from Yu-Ju Hong: When running many managers (e.g. > 10) in parallel on a decent machine, there is often a number of pymp-xxx directories left in /tmp after the run.
After some digging and debugging, I think the cause is that multiprocessing.managers.SyncManager waits for the manager process to shutdown and join with a timeout of 0.2s, and this timeout is way too low. This leads to processes being forced to terminate before cleaning up the temporary directories properly. Could the timeout being raised a bit, or at least allowing the timeout to be set when creating the SyncManager through Manager()? ---------- components: Library (Lib) messages: 219767 nosy: yjhong priority: normal severity: normal status: open title: multiprocessing leaks temporary directories pymp-xxx type: behavior versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21664> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
