New submission from David M. <davidm...@protonmail.com>:
Awaiting multiple times on a single task that failed with an exception results in an unbounded increase in memory usage. Enough repeated "await"s of the task can result in an OOM. The same pattern on a task that didn't raise an exception behaves as expected. The attached short script ends up using more than 1GB of memory in less than a minute. ---------- components: asyncio files: multi_await_exception.py messages: 414739 nosy: asvetlov, davidmanzanares, yselivanov priority: normal severity: normal status: open title: Awaiting multiple times on same task increases memory usage unboundedly versions: Python 3.10, Python 3.11, Python 3.7, Python 3.8, Python 3.9 Added file: https://bugs.python.org/file50664/multi_await_exception.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46954> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
