There is a config entry named "maxConnectMessageSize" that you can use to increase this limit, or set to zero to disable the limit. I could not find it in the Online Help either.

I guess the limit is meant to keep connects to a reasonable size, and maybe too big connects can have adverse effects on performance, but I can't tell you much about that.
