As no-one has responded yet, and stating the obvious: the Microsoft
Knowledgebase might have information on that. Perhaps there is an
explicit or hidden registry option or something to limit the amount of
connections per server.

per_source = 3 is a bit low and lower than what's recommended for IMAP,
for instance - I'd set this to 6 if possible, and bump instances
accordingly (perhaps 15) if your server can stand the memory load.

If it happens without firewall, then go on debugging. If it goes away
when removing/disabling the firewall, check if your configuration is
correct - if the firewall is stateful, there may be a problem, perhaps
with connections timing out too soon.

Sorry for not being able to be more helpful on this.
