Question about configuring activemq for sending large messages

[dchazin <ch...@yahoo.com>]

I am having problems with the following configuration and I hope someone can
shed some light on my problem.
I have a persistent topic with one producer and one consumer. The producer
puts out 5 messages per hour. Each message is approximately 45MB in size and
is sent as a serialized java object.
I have turned off producer FlowControl and increased the producer memory
limit in the broker and also turned off timeouts in the broker. However I
consistently get ChannelClosed exceptions after a few messages are sent.
I have tried disabling timeouts on the producer and consumer and when I do
this the producer appears to deadlock (i.e. hang) after less than 10
messages.
Any suggestions would be appreciated.

Something that may help to reduce the memory usage by the broker is a
prefetch of 1 for your consumer and lazyDispatch=true for your destination.
This should ensure that only one message is kept in memory by the broker at
a time.

What does jconsole say about your broker (w.r.t memory usage) when your
broker is hung?
