Subject Re: any activemq version that can handle >1mb message size
Date Mon, 07 Jan 2008 16:40:21 GMT

Hi

The v5 server leaks memory. (Possibly the client libs too.)
I created a toy application:
Program-A-loop: consumes a msg from queue q1 and puts it on queue q2. 
Program-B-loop: consumes a msg from q2 and puts it on q1.
A loop that will stress the server, I know:)

Initially, I start with some msgs of about 600k (any size would do) on queue
q1.
After a while the server occupies a lot of memory.
