Its seems that the Bonita Engine is trying to execute a job for a execution that doesn't exist anymore. Do you reproduce this systematically? wich are the steps to reproduce this issue?

Hi all friends

My fellow "Temple of Steel" has found that it happens when there are two versions of a subprocess and one of them is disabled , and several father cases process of this subprocess are already alive.

Then BOS write this error in log every five seconds

The solution is to remove all this father cases with the subprocess disabled

Hope this help

Regards

How do I identify the father cases with sub-processes disabled to remove them?

The bug BBPMC-110 was fixed in the version 5.10.2 (already available to download).

You seem to the same issue as Andrés (https://bonita.atlassian.net/browse/BBPMC-110).

Do you have a process containing a boundary timer on multi-instantiated task?
