Charlie Mordant updated AMQ-5168:
---------------------------------
Fix Version/s: (was: 5.9.0)
> CLONE - ActiveMQ 5.x does not support the notion of a grace-period for heart
> beats as supported by the STOMP protocol
> ---------------------------------------------------------------------------------------------------------------------
>
> Key: AMQ-5168
> URL: https://issues.apache.org/jira/browse/AMQ-5168
> Project: ActiveMQ
> Issue Type: Bug
> Affects Versions: 5.9.1
> Reporter: Charlie Mordant
> Assignee: Timothy Bish
> Labels: easyfix
>
> Regarding the configuration of heart beating the STOMP protocol spec states:
> "- because of timing inaccuracies, the receiver SHOULD be tolerant and
> take into account an error margin"
> However, it appears that ActiveMQ 5.x is not tolerant of any error margin.
> Despite the fact that the spec says SHOULD rather than MUST it would make the
> implementation of STOMP clients easier if the error margin was published.
> As the broker aggressively enforces the heart beat timeouts false failover
> attempts can result.
> Apparently Apollo supports an error margin of 1.5x the configured heart beat.
> If it could be made configurable that would be even better!
