Can anyone tell me if there is a limit on the number of outgoing

Each TCP-connection needs an unique port-kombination. There are only
65535 TCP-ports, so Putty can not open more then 65535 connectons to
the same port on the server.

But there is a MaxSessions variable in sshd_config that limits the
number of incoming sessions. It's typically set to 10 as that's the
default. Good luck having an account on 65535/10 systems to be able to
hit the outgoing limit before enountering the incoming limit.

The limit is not 65535 connections at all, the limit is
65535/remote server :-D.
