Hi Team, I’m running a Gatling simulation on Jenkins. Whenever I start parallel execution of simulations (more than 2) it’s never ends. In Jenkins console output showing active: 0, and elapsed time only getting changed. Is there a way to run parallel execution for multiple simulation. I am using Gatling 3.8.4 version. Thanks, Vikram ---

Hi, First, please upgrade to Gatling 3.9.5. Then, if you still experience an issue after upgrading, please provide a reproducer so we can investigate. Note: if the issue is with your Jenkins infrastructure, there’s nothing we can do. You might want then to consider Gatling Enterprise that provides a better CI solution where Jenkins is only used for scheduling and Gatling Enterprise takes care of provisioning and executing the Gatling tests. ---
