A small volume of traffic, as in not that many stanzas. This would
explain why large services like jabber.org have not seen this behavior,
since there is a continual stream of traffic between the two domains. As
I said, they may have some kind of automated timeout if the traffic
between your service and Google Talk is irregular or intermittent. This
is a second-hand report so I have not verified it with folks at Google.

Sorry, "federated link" was a fancy way of saying "s2s connection".

Since I don't work for Google, I will not attempt to speak for them.
