I modularized my transactions into their own scripts and call them from a controller script based on percentages. I did this instead of combining all scripts into one for size and maintainability reasons and for the ability to run each singularly if needed (baselining and debugging).
In the test suite if I set up a single group of 50 v-users to start (ramped up over time, i.e batches), the test hangs. If I create 5 groups of 10 v-users, all enabled at the beginning of the test (again ramped up over time), it hangs as well. If I only enable the 1st group of 10 and let them start and then enable each group manually and start them over time manually, it runs fine. I also tried this with 10 groups of 5 with the same results.
I suppose this is an insight into how to avoid an execution issue.
Re: Test Hangs
Do you have any idea why/where it is hanging from the error/audit logs?
