i have this other problem
when i run my server, it works fine, and i get the connection from the client, but right after if i test it again
i get
ERROR on binding: Address already in use
but if I change the port, and compile, then change the port to what it was before, and compile, then run it , then it works again, then the whole thing happens again
does anyone know why this could be happening?

BUGS
The network synchronization between client and server instances is weak, and does not prevent incompatible options from being used on the
two instances. The method used for retrieving work completions is not strictly correct, and race conditions may cause failures on some
systems.
