You can enable logging for redelivery (retry) and set a high logging
level like WARN etc. so you can notice it in the logs.
<xs:attribute name="retryAttemptedLogLevel" type="tns:loggingLevel"/>
<xs:attribute name="logRetryAttempted" type="xs:string"/>
But using 0 ought not to attempt redeliveries, unless you have
<onException> or something else that has a policy which overrides the
<errorHandler>.
