> [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
> Priority: Minor
> 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 idle timeout is configured using the context variable
> {{qpid.port.heartbeatDelay}}, the broker closes the connection if the other
> peer does not send a heartbeat frame within the value specified in
> {{qpid.port.heartbeatDelay}}. However, the broker should interpret the value
> of {{qpid.port.heartbeatDelay}} as half of the actual timeout, as recommended
> by the AMQP specification.
> *Note:* The AMQP .NET Lite library (version 2.4.11) can be used to reproduce
> the issue, as it sends heartbeat frames at intervals matching the idle
> timeout specified in the AMQP OPEN frame.
