Hi, I've faced this issue when using logging.handlers.SocketHandler AWS TCP balancer. AWS balancer uses 60 second time-out by default (max 4000s), thus resulting in lots of closed sockets during inactive periods. SocketHandler.send() drops current message on any socket errors, so only next message gets logged. I've tried to reproduce this using Lib unit tests, but didn't find any easy way to close() socket on test server side. Sample client/server scripts attached, server output: Got connection from: ('127.0.0.1', 58044) Got message: b'Message #1\n' Got message: b'Message #2\n' Got connection from: ('127.0.0.1', 58045) Got message: b'Message #5\n' Server closes incoming connection is 2 seconds, client looses messages #3 and #4. ---------- components: Library (Lib) files: Archive.zip messages: 366920 nosy: Oleg Nykolyn priority: normal severity: normal status: open title: SocketHandler silently drops log messages on re-connect type: behavior versions: Python 3.8 Added file: https://bugs.python.org/file49080/Archive.zip _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40352> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
