Thread: No mention about somaxconn
Currently there's no mention about net.core.somaxconn parameter needs to be adjusted if max_connections is large and UNIX domain socket is used for connection. Since the default for the kernel parameter is small (typically 128), it is easy to hit the limitation and you will get errors something like: could not connect to server: Resource temporarily unavailable I don't know if this should be applied to other OS as well though.

Yea, that'd be good. Care to suggest a patch? Greetings, Andres Freund
