I am working through similar symptoms from yesterday (FreeBSD 11p2 kernel + p7 userland, haproxy 1.6.10) where all 4 load balancers in different regions locked up, around the same time. I'm also struggling to identify anything that we did that might have triggered this. The only correlation I've found so far is a temporary loss of network on our frontend web servers, and we seem not to have had anybody deploying stuff around that time. - stats page is inaccessible - front end & back end seem to be disconnected - there was only a single haproxy instance running - dtruss showed only kqueue(0,0,0....) = 22 (EINVAL) continuously - system logs are blank, although shortly afterwards the box panicked completely A+ Dave
