Hi, I change my setup as you suggested, so I have now 1 user with 100 requests, reading randomly from a number of files in a folder without any memory problems. And I am using Constant Throughput Timer to adjust the message per minute.

The JMS API only seems to allow TextMessage types to be populated from a String, so the entire file will have to be read into memory. > I setup two Thread Groups (one with a single publisher, the other with a > single subscriber) > > In my test case I need to test 6 messages per minute, so I set number of > threads (users) to 60 and Ramp-up to 600 since I want to run the test > longer than a minute. > > (maybe my setup is not right for what I am trying to accomplish) You need a Constant Throughput Timer to set the appropriate rate. The ramp-up does not control test duration directly, that mainly depends on the number of samples sent (loops) and the sample rate. I suggest you try experimenting with a dummy test using Java Samplers to see how the Timers work. > So after a while I get the out of memory error.
