---------------------------
> After AMQ-7079 abortSlowAckConsumerStrategy aborts connection by default

> Key: AMQ-7081
> URL: https://issues.apache.org/jira/browse/AMQ-7081
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Reporter: Simon Lundstrom
> Assignee: Gary Tully
> Priority: Major
> Attachments: AMQ7081Test.java

>
> The fix of AMQ-7079 introduced a breaking change bug since the default value
> of {{maxSlowCount=-1}} was longer enough for {{abortSlowAckConsumerStrategy}}
> to just configure the slow consumer detection but it started to disconnect
> the consumer as well.\{{}}
> Setting {{maxSlowDuration="-1"}} doesn't disconnect the consumer though but I
> don't think we should change the old default behavior.
> Pre AMQ-7079 fix:
> {code:xml}
> <abortSlowAckConsumerStrategy checkPeriod="1000" maxTimeSinceLastAck="3000"
> maxSlowCount="-1" />
> {code}
> worked before in just detecting a slow consumer. consumer was *not*
> disconnected.
> After AMQ-7079 fix:
> {code:xml}
> <abortSlowAckConsumerStrategy checkPeriod="1000" maxTimeSinceLastAck="3000"
> maxSlowCount="-1" />
> {code}
> disconnects the consumer; ActiveMQ logs:
