Does this seventh server happen to be always the same one or it doesn't
matter wich one?

The reason for this message could be simply that your seventh server
has a firewall that only allow some ports (like 3050) to pass through.
Events are a second connection to the server through a different port.
The connection for this seccond port is made from your server toward
your client machine. If i remember corectly it is a port from 1024 to 2048
or whatever user ports redht allows.

Another reason could be that you have to many ib_events and i think every
one has its own private connection, so it could be that you take up all user
ports from win2000, but i don't think that it's the case.
