New submission from renlifeng: If func creates lots objects and appends them to a list, and runs over and over, pool.map(func...) will eventually eat up all memories. Cleaning the list at the end of func does not help.
One can reproduce by running the attached file. By contrast, after replacing ThreadPool with the theading module (see the commented out lines), memory usage will not grow continuously. By the way, I used what's in Debian stretch, i.e. python 2.7.11 and 3.5.1. ---------- components: Library (Lib) files: cvtest5.py messages: 260716 nosy: renlifeng priority: normal severity: normal status: open title: multiprocessing.pool.ThreadPool eats up memories versions: Python 2.7, Python 3.5 Added file: http://bugs.python.org/file42012/cvtest5.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26418> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
