Error Message :
N/A

In some cases "Run At" exceptions are not executed.

It is not yet entirely clear which circumstances invoke the issue. Elements that may play a role are:

• Rule of the Task is NEVER
• Multiple "Run At" exceptions are added to the Task to run the Task for one-off executions
• The "Run At" exceptions are recycled (an exception that has already run in the past is re-used for another execution in the future) 

Cause type:
Defect
Root Cause: Still being investigated.

Update to a fix version listed below or a newer version if available.

Workaround :

• When the list of "Run At" exception becomes long delete old entries
• When creating a "Run At" exception for a future run always create it by using the "Add" option, don't recycle
