Using many Insight post functions stops some of them to execute

Issue Summary

Using many Insight post functions stops some of them to execute.

It is suspected this is due to race condition that can occur when there are many functions executed (e.g. 4 or more).

Steps to Reproduce

1. Set up 4 or more different Insight post functions in your workflow
2. Publish the workflow
3. Use the transition with the defined post functions.

Expected Results

They should all work and be executed during the transition.

Actual Results

Some post functions will work but the others will not.

Workaround

In some cases, the following may help:

• Re-arrange the order of the post functions.
• For the post function that does not execute, add the following Groovy validator, that will delay the execution of the post function by 1 second:

  sleep(1000)
  return true
