AW: Workflow Stops without error in background task statusready

Hi All,

the error sometimes also occurs at the beginning of the process at the first background task - no parallel branch exists at this moment and no update is done in background!

Any ideas are welcome.
Thanks in advance

HI Mike,
Hi All

yes there are some simultaneous forks in Definition. One in the main flow, and two in each subflows. After the deletion of the forks still the same problem.

But the lock can be the reason. In a dialog task I make at the end an update on a czustom-table. In the next task a background step updates the same database.
Can this be the program? Commit work is not set in the dialog or background task

Regards

Christian Nicklas

Uh, hold on. You say RSWERRE restarts it. So in other words they SHOULD
all restart themselves after a while (20 minutes)...  yes?

In that case might it be some kind of locking conflict? - pick your
process apart for simultaneous forks or DB updates which might still be
active or other similar things.
How is RSWERRE scheduled (SWWD)?

Failing that, OSS.

Cheers,
Mike
