Hi, i have a rails app using unicorn + nginx.
Last month my app started to get really slow and giving me error 502.
Unicorn log doesn’t show nothing, either my rails app log.
But looking at nginx error log, i get numerous:
[error] 1837#0: *263157 connect() to unix:/tmp/.app.sock failed (11:
Resource temporarily unavailable) while connecting to upstream,
What could it be? What causes this?
If I change from socket to tcp connection, my tcp connection doesn’t
this error, but gets time out.
Thanks for any help.
