Re: ActiveMQ stops sending messages to Queue Consumer in case of
consumer not acknowledging messages
Yes, I am calling commit on the session but only after receiving say X number
of messages. Consumer will accumulate X number of messages before processing
and acknowledging them.
This X is configurable number. We tried with 500 and consumer was receiving
only around 350 messages. Messages which are enqueued and pending was around
5000.
Number of messages sent by JMS varies as per the size of message (larger the
size, less number of messages received by consumer). After sending say 350
messages to consumer, JMS waits till acknowledgment before sending further
batch of messages.

Increasing the value of the /memoryLimit /attribute in the
/conf/activemq.xml/ configuration file solved my issue. JMS started sending
messages without waiting for acknowledgement.
Thanks SuoNayi for exactly pointing out the issue.

Memory usage limit can contriubte this issue.
Since your queue's memory is exhausted by those messages that were dispatched to consumers but not acked by consumers.
When broker page more messages from the store it will check if the queue has enough memory space to load new messages,
if no then no more new messages will be loaded and dispatched to conumers.I suppose the memory usage limit of your queue is
the default value(1MB),then when 1MB size messges have dispatched to your consumers and no acks come back,
then broker can not dispatch more messages due to memory usage limit.
