Try switching to a different reactor. For example, the select reactor
is limited to FD_SETSIZE open sockets. This is usually around 1000, but
could be 500 on some systems. Poll reactor is limited to the "open
files" rlimit which can be raised by superusers. IOCP reactor has no
arbitrary limits, I think.
