Activiti creates multiple Runtime Tasks for a single synchronous process instance

HiI was implementing Activiti in a personal project of mine and was facing a peculiar issue. So, my process is a sequential process with no async or parallel executions. Now, when I complete one task, it is removed from the ACT_RU_TASK_ table and the next task's entry, according to the process defin

Hi Himanshu,

In a sequential process the ACT_RU_TASK should only contain one entry for a process instance. Maybe you can share your process definition and a screenshot of what you see in the database. Would be good to add some additional remarks about when exactly you see this happening.

Best regards,

Hi trademak

Thanks for the prompt reply. I am attaching a screenshot of the shot for a process instance for which we have multiple runtime tasks (this is ACT_RU_TASK table). Due to a non-disclosure clause associated with my project, I won't be able to provide you the process definition. However, I can provide you specific details with regards to it in case you require. Apologies for that.

Can you think up of some particular reasons due to which such a behaviour may be seen? Could it be due to some configuration associated with spring or the db (mysql) or while defining the process definition?

According to ACT_RU_EXECUTION, the process with the pid 573466 is still at print documents stage.

No, and the scenario sounds very unlikely.

Without process definition, we are not able to say anything. The log lines you posted there are meaningless for us without context.
