It's probably not a problem on your end, but you can use the
Configuration Editor, to check the connection limits. See
if yours are radically different than mine.

I think it's the second, third, and fourth line in that example
(as I have three server entries in my TB setup). But don't quote
me on that.
The Configuration Editor has no "undo" function, and is very
dangerous. Don't erase any lines in there, or you'll be sorry.
Ask me how I know...
