> Key: AMQ-5483
> URL: https://issues.apache.org/jira/browse/AMQ-5483
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.10.0
> Reporter: Gary Tully

> Labels: messageGroups
> Fix For: 5.11.0
>
>
> by default, consumers are ordered by consumer priority and number of assigned
> message groups. The group assignment lru map can evict group associations,
> but the eviction is only noticed on next use of the groupid at dispatch,
> which may never happen. This leaves consumers less likely to get new groups
> assigned in error. The combination of a low cache size and long lives
> consumers should allow even distribution.
