-----------------------------
Resolution: Fixed
> CQ event might be missing if HAContainer enables eviction
> ---------------------------------------------------------
>
> Key: GEODE-9596
> URL: https://issues.apache.org/jira/browse/GEODE-9596
> Project: Geode
> Issue Type: Bug
> Components: cq
> Affects Versions: 1.12.0, 1.13.0, 1.14.0
> Reporter: Eric Shu
> Assignee: Eric Shu
> Priority: Major
> Labels: GeodeOperationAPI, pull-request-available
> Fix For: 1.12.5, 1.13.5, 1.14.1
>
>
> The issue exists when proxies are enqueue cq messages to each HARegionQueue.
> As HAContainer enables eviction, the value (ClientUpdateMessageImpl) can be
> evicted. The next proxy needs to fault in the message when enqueues the event
> to its queue and _clientCqs map is lost during that exchange.
> The operation will create a new _clientCqs map in this case, and if a
> dispatcher thread is processing the already queued event and access the map
> at the same time, it will not find its client in the cq maps, and thus cause
> the cq event is lost.
