Since the log isn't very helpful, here's an explanation:
Friday's dev.9 has my patch to fix a shutdown timing issue. There was a list of connections per [e]poll, as well as an overall list of connections; both used on shutdown. There were multiple paths for deleting the polling structures. This was old code. So I'd removed the list of connections per poll, and moved the code for deletion into the polling task itself, ensuring only one path. "There can be only one." The lock for the removed list was now hardly needed, but still in place. It locked only 5 "channel" objects with significant potential for transaction contention. I've been able to reproduce a hang during shutdown (while running pynfs under gdb with both debug and address sanitizer). Now I've removed that lock entirely (using atomics), and Frank kindly pushed a version so that nobody else would be harmed. Because this was an old lock in the fast polling connection and per transaction call path, that path should be a mite faster. The only remaining lock is per connection/transport, so should be better distributed and have much less contention. On 9/19/17 3:16 PM, Frank Filz wrote:
