But, actually, nevermind: we have explained the failures you were seeing in the test setup, but a multiple-active-archiver situation still doesn't explain the original situation of incoming connections getting blocked. What I'd suggest is resuming the test after making sure you've killed off any old archivers, and seeing if you can make any progress on reproducing the original problem. We definitely need a multiple-archiver interlock, but I think that must be unrelated to your real problem. regards, tom lane
