-------------------------------
Summary: LRU cached message group map eviction is not reflected in
consumer assigned counts
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
Assignee: Gary Tully
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.
