As Pavel notes in https://issues.apache.org/jira/browse/QPID-3264, you want to ensure that heartbeats are "at most 1/2 of TCP retransmission overall-time (that by default around 15 minutes on Linux and 12 seconds on Windows)". This prevents the situation where the client gives up on the connection and yet the broker assumes it is still established.

A footnote to that effect could be added to the documentation in the appropriate places (e.g. table 2.4 in Programming Guide and section 7.3 in User Guide).

Should this not be assigned to a documentation component now?
