QPID-8293: limit the number of messages that can be purged in a single sweep
> queue cleaning locks up connections
> -----------------------------------
>
> Key: QPID-8293
> URL: https://issues.apache.org/jira/browse/QPID-8293
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker
> Affects Versions: qpid-cpp-1.38.0
> Reporter: Gordon Sim
> Assignee: Gordon Sim
> Priority: Major
> Fix For: qpid-cpp-1.39.0

>
> The queue cleaner thread currently holds the queue lock while purging all the
> expired messages. This can cause worker threads to be blocked waiting for
> this lock. Particularly when expired messages are logged, this can result in
> those threads being blocked for significant periods of time during which they
> are unable to handle heartbeating or even closing of the connection.
