Errno::ENOTCONN - Socket is not connected

Hi, today I tried runnig puma on production server (MRI, but still wanted to check out the memory footprint), but I'm getting Errno::ENOTCONN after running puma for some time (in the end site is not responding at all)

Running on shared host (can't really check nginx logs):

ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-freebsd9.2]

Puma config (+ running on UNIX socket):

threads 1, 8
workers 2
preload_app!
worker_timeout 60

After running it for whole day and bunch of restarts I finally had to revert back to unicorn (running fine on same server for over a year). Any ideas what might be causing this? 😢

Ah. FreeBSD must return that error for unix sockets instead of returning nothing like linux does. Easy fix.
