Hi Dmitry, We are using Linux OS for the application server and Windows for JMeter. We are getting jav.lang.OutOfMemory error. Our JMeter machine is 32 bit processor with 4GB RAM.

Sorry, I skipped your messages about 4 users test. It is strange. What OS do you use? What memory usage do you have in the task manager? Try to inspect JMeter with some profiler tool (JConsole or YourKit Java Profiler, etc). What kind of memory JMeter exceeded (Heap Memory, PermGen space)? DK> How many threads do you start for your test plan? DK> What kind of OutOfMememory Exception do you have?
