[jira] [Resolved] (AMQ-4226) Broker destination zero prefetch and
RAR endpoint listener are incompatible b/c RAR is starved of messages - log
an error to highlight
[ https://issues.apache.org/jira/browse/AMQ-4226?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Gary Tully resolved AMQ-4226.
-----------------------------
Resolution: Fixed
error now logged by the RAR if zero prefetch is in effect. Condition could be by design if a rar consumer needs to be weaned for some reason, hence the use of the log.

> A broker configured zero prefetch will starve the RAR of messages. The consumer is now aware of the zero prefetch and will log an error if it sees a prefetch value of zero.
> RAR is push only so it needs to have a prefetch > 0 for normal operation. Setting prefetch to zero broker size is a way of preventing dispatch if necessary.
