I would like to raise awareness about a very serious bug that affects AE v11.2.5 & v12.0.2.


An error has been fixed where starting an inactive task within a workflow with "GO Immediate" lead to an endless activation of this task. Only cancelling the workflow cancelled the activation of tasks.
When this bug hit us, it caused almost ten million tasks to be added to the activity table within a matter of minutes. Needless to say, this had a negative impact on the system, and it took hours to remove the erroneous rows from the DB and get the system back up and running. We were very lucky that this did not happen in the production environment.

If you are running an unpatched system, do not use the GO Immediate function with inactive workflow tasks.

See known error article 10015 for more details.
