[AMQ] Queue size grows infinitely

[Balamurugan Seenivasan]

Hi,

We notice an issue recently in production where the messages in queue size 
grows disproportionate to the number of messages actually produced.
Queue size grows close to 3 million in about 3 days while the actual messages 
produced are way less than the actual queue size.

Here is one snapshot of how the queue looks like when actual messages produced 
are only around 60000.
794712 (pending)    8(consumers)    679793(enqueued)    507419(dequeued)

We use browseMessages extensively (from around 50 threads) using selectors like 
'JMSCorrelationID LIKE <data>%'.
We notice this issue only with those queues we use browseMessages against. 
Not sure if there is a link to usage of browseMessages.

AMQ version: 5.16.3 (windows)
Persistence: 
Yes (Microsoft SQL Server 2019 on Linux (Ubuntu 16.04.6 LTS) <X64>, 
mssql-jdbc-9.4)
config:
              <persistenceAdapter>                       
                        <jdbcPersistenceAdapter dataDirectory="activemq-data" 
dataSource="#mssql-ds" lockKeepAlivePeriod="5000">
                                <adapter><transact-jdbc-adapter/></adapter>
                                <locker>
                                        <lease-database-locker 
lockAcquireSleepInterval="10000"/>
                                </locker>
                        </jdbcPersistenceAdapter>
                </persistenceAdapter>

Appreciate any help/pointers narrowing down the cause.
