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?
*** Bug 752510 has been marked as a duplicate of this bug. ***
Committed revision 76539. "Requests that heartbeats be sent every N seconds. If two successive heartbeats are missed the connection is considered to be lost. Heartbeats should be defined to, at most, 1/2 of TCP retransmission overall-time. By default, TCP retransmission time is around 15 minutes on Linux and 12 seconds on Windows."

Neither of following documents contain cited paragraph Red_Hat_Enterprise_MRG-Messaging_User_Guide-2-web-en-US-2-15.el6eng Red_Hat_Enterprise_MRG-Programming_in_Apache_Qpid-2-web-en-US-2-5.el6eng doc.stage: Red Hat Enterprise MRG 2 - Programming in Apache Qpid Red Hat Enterprise MRG 2 - Messaging_User_Guide Unfortunately Red_Hat_Enterprise_MRG-Programming_in_Apache_Qpid-2-web-en-US-2-1.el6eng is deleted already, but it seems the above mentioned commit was omitted or just not merged to package. Package changes-log proves that, no comment about heartbeat doc update neither in Red_Hat_Enterprise_MRG-Programming_in_Apache_Qpid-2-web-en-US-2-5.el6eng nor in Red_Hat_Enterprise_MRG-Programming_in_Apache_Qpid-2-web-en-US-2-2.el6eng Tim, could you possibly doublecheck whether I look at correct packages, please? -> ASSIGNED with NEEDINFO
As far as I checked neither documentation stage nor package in Brew contains patch which would allow me to put this defect to VERI. Hi Cheryn, could you possibly apply above patch and let me know where I can check it, please? (either rpm or doc. stage)
Above cited paragraph (comment 4) was added to Programming_in_Apache_Qpid docs. -> VERIFIED
