-------------------------------
Summary: Log a warning if paging in for queues blocks on usage
constraints
Key: AMQ-6854
URL: https://issues.apache.org/jira/browse/AMQ-6854
Project: ActiveMQ
Issue Type: Improvement
Components: Broker
Affects Versions: 5.15.0
Reporter: Gary Tully
Assignee: Gary Tully
Priority: Minor
Fix For: 5.16.0
In a case where the cache is disabled but there is no flow control, messages
can continue to be produced directly to the store. Dispatch from memory will
continue and paging in will work in the normal way.
However it is possible for queues to starve each other when paging in, such
that some queues with no messages in memory will not be able to page in.
In this case, it is important that we log a warning to have some indication in
the logs that consumers may be starved such that memory limits can be increased
if necessary.
