Closes #89035. We can reopen it if it continues to fail
Working on a guess here, if the server tasks are unblocked too soon, they might quickly process the request, and the client will assign another request to that connection. As a result, some server connections may never receive a request, which causes the test to time out.
The main change is unblocking the server tasks after we've read all client requests.
Then I also changed the
WhenAll
s toWhenAllCompletedOrAnyFailed
to see if we can get better error information.Edit: While that race might have happened, after switching to
WhenAllCompletedOrAnyFailed
the logs show that the server was rejecting connections. Not seeing failures anymore after raising theListenBacklog
