I very much doubt that this is an internal gnet limit.

There is a system limit for the maximum number of file descriptors that a user 
on the system can have open at the same time. You can see this limit when you 
type

% ulimit -n

in a bash shell (different for other shells).

This limit seems to be 1024 by default on a lot of systems, so if you want 
more concurrent connections you will probably need to change this setting in 
your system settings [*].

Of course it is also possible that the same limit applies to the server.

[*] for what it's worth, you can find some pointers on how and where to change 
that limit on your system here:
