One thing I'd like to suggest is that this error would be better if it had more information about what resource wasn't available.

The error is EAGAIN caused from the socket() system call.

Are you sure? My Linux's man page or UNIX98 man page doesn't say that socket() could ever return EAGAIN. If it's out of file descriptors or something else, it should return EMFILE or ENFILE.

connect() however can return EAGAIN:

   EAGAIN No  more free local ports or insufficient entries in the routing
          cache. For PF_INET see the  net.ipv4.ip_local_port_range  sysctl
          in ip(7) on how to increase the number of local ports.

It can't be about local ports since UNIX sockets don't use ports.
