New submission from Andrei Zene <andrei.z...@outlook.com>:
In an application where we were handling incoming requests in new threads, we noticed that the memory usage grew over time. After trying to understand what's going on, i was able to reproduce this with a smaller python script that i've attached. What we do: - start a thread - the thread allocates some memory - at some point later we join the thread Notice that this seems to be more like a race-condition because it doesn't reproduce without adding some delays between the creation of different threads. I've added a comment in the file that basically commenting one time.sleep makes the leak to not reproduce anymore. On the other side, I was able to reproduce this consistently with every version of python on mulitple systems but only on Linux. On windows it doesn't reproduce. ---------- files: threading_leak.py messages: 399267 nosy: andzn priority: normal severity: normal status: open title: Threading memory leak type: performance versions: Python 3.10, Python 3.11, Python 3.6, Python 3.7, Python 3.8, Python 3.9 Added file: https://bugs.python.org/file50206/threading_leak.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44871> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
