Summary: [Broker-J] Halve the configured idle timeout
Key: QPID-8680
URL: https://issues.apache.org/jira/browse/QPID-8680
Project: Qpid
Issue Type: Improvement
Components: Broker-J
Reporter: Tomas Vavricka
Fix For: qpid-java-broker-9.2.1
[AMQP 1.0
specification|https://docs.oasis-open.org/amqp/core/v1.0/amqp-core-complete-v1.0.pdf]
in Chapter 2.4.5 states '{_}Connections are subject to an idle timeout
threshold. The timeout is triggered by a local peer when no frames{_} _are
received after a threshold value is exceeded. The idle timeout is measured in
milliseconds, and starts from_ _the time the last frame is received. If the
threshold is exceeded, then a peer SHOULD try to gracefully close the_
_connection using a close frame with an error explaining why. If the remote
peer does not respond gracefully within_ _a threshold to this, then the peer
MAY close the TCP socket._ _Each peer has its own (independent) idle timeout.
At connection open each peer communicates the maximum_ _period between activity
(frames) on the connection that it desires from its partner.The open frame
carries the idletime-out field for this purpose. *To avoid spurious timeouts,
the value in idle-time-out SHOULD be half the peer’s*_ {*}_actual timeout
threshold._{*}'
When the incoming idle timeout is configured using the context variable
{{{}qpid.port.heartbeatDelay{}}}, the idle timeout value sent in the AMQP Open
frame is not halved, as recommended by the AMQP specification.
For example, if {{qpid.port.heartbeatDelay}} is set to 60, the Open frame sends
an idle timeout value of 60000.
