Hi
First we need to find out if any instance of the task TS00008046 is generated or not and then check why isn't it going to any user.
Did you try checking in SWI2_FREQ by specifying the task TS00008046 in task filter and the date range AFTER the issue was resolved? Are there any instances of this task generated in the system?
If yes, do we see the agent in the log for that task ? if not, what do we see there? any erorr? or no agents?
regards,
Modak
