Jmeter loop Count 'forever' does not run forever

Question

I have created a jmeter scrip for 25 users to login to system and perform some functions. I wanted to run that run that test plan forever. So i have selected Loop count "forever" option in test plan.But thread group doesn't run forever and its stoped automatically. Why this is Happening? Structure of Test Plan as below;

• Test Plan

• Thread group

  • HTTP Request Default
  • HTTP Cookie Manager
  • HTTP Cache Manager
  • CVS Data Set Config
  • Transaction Controller for Login
  • Transaction Controllers for Other functions
  • Transaction Controller for Logout
  • View Result Tree
  • Response Time Graph

Answer 1

Double Check your CSV Data Set Config element and make sure that:

• "Recycle on EOF?" is true
• "Stop thread on EOF?" is false

Answer 2

This is also can be done using loop controller.

Use 'loop controller' under 'Thread group' and segregate all your requests('25 users to login to system...') here, and keep Transaction Controller out of loop.

Here, it is also possible to use 'Simple Controller' and segregate these requests.

Run jmeter script's using console, and disable components like 'View Result Tree' and 'Response Time Graph' it is best to configure jmeter for memory leaks.
