Hello everybody,I am experiencing a very strange error here:My Main-Process should start a Subprocess and after that has finished, the Main-Process should just exit.The Subprocess is a very long running one, and after some time, the Main-process seems to be starting the Subprocess again. And after s

Hi,

This is not information to say anything about your problem.
Do you see any errors in the log? Is there a specific point in time when the sub process is started again?
Do you have a timer event defined in the main process?

Best regards,

Hi, thanks for your answer.

I´ve attached the process image.

The process creates a UserTask and programmatically this UserTask is "completed".
The next step is that a ServiceTask is called which performs certain actions and after that the SubSprocess is started.

Now comes the weird thing: The SubProcess, and only the SubProcess is instantiated again and again.
Note: Note the complete process after completing the UserTask, not the ServiceTask - only the SubProcess.

There is no timer, and I can see in the process structure, that the parent of the SubProcess is always the same.

if your subprocess is async/transactional, I it might be that the 'jobexecutor', responsible for async things, retries it if it takes more than 5 minutes..

I tried it with sync and async if I recall correctly.
I will test that again.

Do you know if there is a way to configure that jobexecutor to ignore long-running processes ?
Our processes sometimes run up to 5 days …

The jobexecutor should afaik not be involved if it is non-async. But it still might if the subprocess is transactional. No clue for a solution then

Do you know how I can find out whether the subprocess is transactional ?

Or do you know a way for the newly created subprocess to terminate itself if another process already exists ?

Hi, this thread can be closed.

It was in fact the JobExecutor and the task was set to async.

This doesn´t free me from all of my problems, but this particular one is solved.
