Jmeter version 4.0
Working case: Created performance tests on application API's using jmeter. I have 50 unique users with zero rampup time and ran the script for 50 users, execution went successfully and no assertions failed.
Not working case: Now I ran the same script for 15 mins duration through jmeter scheduler where start delay is 0. In this case script is failing at login with error "CRPF validation" for some users.I also increased start delay and rampup time but no luck.
I am not sure why this failing as i am capturing the user token correctly and passing to the login api. It is working fine in first case but always failing second case.
Drupal controls login.
Any help is greatly appreciated, as i cannot run the test for certain duration.
Thanks, Ravindra
