There's no limits in Twisted itself that would cause that, so it's
likely in the kernel. For example -
You may have the free TCP port limit range, since you are doing so many
connections from only two IP addresses. This is not a limit that would
affect you during production, of course; you could see if you can get
higher numbers of connections with more client machines.
