We have an nginx 1.6.2 proxy in front of a Unicorn 4.8.3 server that is frequently reporting the following error:
2015/03/24 01:46:01 [error] 11217#0: *872231 readv() failed (104: Connection reset by peer) while reading upstream The interesting things are: 1) The upstream is a Unix domain socket (to which Unicorn is bound) 2) Unicorn isn't reporting that a child died in the error log (and I verified their lifetimes with ps(1)) Any hints as to what we should look for? Thanks, --Michael
