Not executing complete process after some time for same process definition

Hi guys,

We have observed one scenario in which we have created multiple process instances and all are at user task activity stage after being started of below process definition, intially after user task 1 , service task 3 and 4 were executing and process was completed successfully,
But there were 4 process instances which user did not take any action and it was pending ,
now after some time when user takes any action it completes the user task and completes the process but service task 3 and 4 are not being exeuted . not sure why this behaviour ?

Does the history show which tasks where actually activated when the user task completed?

Hi Niall,

Thanks for replying, the exact use case is service task 3 is mulitinstance sequential subprocess, which in activity history it is tracking but it is not executing the block of elements inside, and history activity table for idle scenario there are aroung 170 + records of each process instances which includes subprocess internal activities but after some time it is having only 9 records

Why do you have a conditional sequence flow leaving the user task?

To display action button to user and unless user clicks on that , process won’t move forward, but that should not contribute to the issue we are facing , right?
