> Key: AMQ-7118
> URL: https://issues.apache.org/jira/browse/AMQ-7118
> Project: ActiveMQ
> Issue Type: Bug
> Components: KahaDB
> Affects Versions: 5.16.0, 5.15.8
> Environment: JDK 8
> Reporter: Jamie goodyear
> Priority: Critical
> Fix For: 5.16.0, 5.15.8

> KahaDB store limit can be exceeded with durable subscribers.
> AMQ with store limit set, we can observe that the usage continues to increase
> AFTER PFC is engaged. Given time, this growth stabilizes. The issue of having
> exceeded the store limit remains.
> See below output from KahaDB dump in attachments:
> This appears to be caused by checkpointAckMessageFileMap. The log files are
> not GC'd, and the KAHA_ACK_MESSAGE_FILE_MAP_COMMAND is replicated and the DB
> log files continue to expand - this can become exponential. Side effect of
> also not checking storage size in checkpoint update can cause the DB log
> files to exceed any set limits. The real critical part is the duplicated and
> leaking Kaha messages which appears to happen with durable subscribers.
