I could finally reproduce it, figure the cause and the fix. The 2.6 backport is missing this patch for evports and kqueue: 698342635 BUG/MAJOR: poller: drop FD's tgid when masks don't match I could verify that it fixes the problem. Without it it fails after 2-3 reloads, and now it survived ~600 reloads without problem. I'm going to backport it, and I don't need to postpone a new 2.6 anymore, so expect a new one soon. Thanks for your report! Willy
