The JWP writes forced traces. The error message in the logs is:

A problem has been fixed where background tasks like search indexing are executed in multiple JWPs or not at all. This leads to search indexes that are not updated. The problem happens if a JWP with a lower instance number is started while there is already a running JWP with a higher number. For example, if AUTOMIC#WP003 is started after AUTOMIC#WP004.
Workaround: The problem can be avoided if all JWPs are started/stopped together.

Solution: Install a fixed version or a newer one:
  • Automation.Engine 12.1.4
  • Automation.Engine 12.2.1
  • Automation.Engine 12.3.0
