Since I upgraded from ES2.5 to ES4 this summer, I have been running into a strange problem about once or twice a month where a user completes a task, but the task just seems to sit in limbo, doing nothing. If I check the process in the Admin UI (Admin UI -> Services -> LiveCycle Process Management ES ->Process Search ->Process Instance ->Process Instance Detail) it shows that the Operation is 'Running', but if i drill down to the task itself, it says that it was 'Completed'. I haven't taken any screenshots of this behaviour, but the screen shots in this post from 5 years ago shows the same behaviour: https://forums.adobe.com/message/3729169
I will note that this seems to happen during a lull in our operations. The most recent time this occurred was around 5:30 PM on Friday (typically, the system stops being used around 5:00 PM). The user clicked the complete button on their form and the task appeared to complete as usual, however it did not move on to the next operation. Fast forward to 1:03PM on Saturday and the task finally decided to move on to the next task and make its way to the next user.
Anything I can do that will make a process continue when I notice that it is stuck in this manner?
Any way I can identify when this is happening (since I never know until someone tells me their task never made it to the next stage)?
Prevent this from happening in the first place?
(I read the suggestions in the discussion linked above and Terminating the task is not a viable option)
