Original output of `procstat -kk` is different from the kernel crash. Original output was from one server. The crash is from the other. Original server, where the deadlock has occurred, has crashed soon thereaft= er. Unfortunately, it did not produce the dump for some reason. Second server had no symptoms, but crashed immediately when traffic was re-routed towards it. And it did produce the core dump. And it't the one we= 're analyzing in here. And seeing `kqueue_scan` in both cases makes us suspect = that these are two symptoms of the same issue. --=20 You are receiving this mail because: You are the assignee for the bug.=
