Seeing issue with latest version of 5.17

We are seeing one odd behavior after upgrading from 5.15 to 5.17.We have a business process with multiple human tasks. When the first task is completed then the process should create a second task, here second task is getting created however three create events are getting triggered with three diffe

I would some more information to fully understand your process and environment. Do you complete the first user task via the Java API? Are you using activiti:async somewhere in your process definition. If you are not using activiti:async how can other members of the cluster be triggered? Please provide some more information.

Best regards,

Yes, we are completing the first task via the activiti API using FormService
   formService.submitTaskFormData(task.getId(), formVariables);

Yes our process definition contains the activiti:async="true" property. But I'm thinking this is to execute the next sequence in asynchronously and not to execute them by multiple job executors, is that not correct?

And also we have configured the asyncExecutor in activiti-context.xml

Yes, only one job executor will execute it.

I assume the job executor is enabled on all nodes? Can you post the process xml that is failing? Is it as simple as start->task->task->taks ?

ganeshr — Fri, 16 Jan 2015 15:13:39 GMT

Yes, Job executor is enabled in all nodes.

Please find the attached process-xml.txt

Yes, job executor is enabled in all nodes.

I'm trying to paste the xml, but the request is going to administrator for approval.

process xml has multiple human tasks and gateways for decisions to invoke next human task.

Is this happening because of job executor enabled in all nodes?

Here is the process xml :

I'm not able to attach or paste the process xml here, as it is allways saying

Re: Seeing issue with latest version of 5.17

ganeshr — Tue, 20 Jan 2015 17:15:34 GMT

Above is the process xml we are using….

If we change human task to Exlusive then one node is executing asynchronously and creating single task, but if the task is asynchronous then all nodes are creating human task. Is this a bug or it is the default behavior?

Re: Seeing issue with latest version of 5.17

jbarrez — Wed, 21 Jan 2015 16:56:27 GMT

ok, thx for the xml. Dont see anything wrong straight away.

Why are you making the user tasks async? Is there any particular reason why you'd want that?
What could be happening is that the task listeners are failing, rolling back the original transaction and then other nodes take over the work (and hence recreating the task). How many times is the task created?

> Why are you making the user tasks async? Is there any particular reason why you'd want that?
     Yes we ant to do in a seperate transaction, first we want to compelete the task before the next task is either created/not created.

   Task listener is not failing, events are firing in all nodes and task is creating in all nodes and out of which only one is committed finally in database. As we are running in 4 nodes, we are ending up with 3 tasks events with 3 different task id's. This is happening only for asynchronous task and for synchronous this is firing only one task event and creating only one task.

Re: Seeing issue with latest version of 5.17

trademak — Fri, 23 Jan 2015 13:08:46 GMT

In the async executor logic a job is only retrieved from the database when it's timed out, so it's really strange that you are experiencing this. It looks like a rollback is done in a couple of cases but the event is being thrown anyway. We'll examine the behaviour and come back to you.

Best regards,

Do we have any improvement in latest release of 5.18 for this issue ?

Re: Seeing issue with latest version of 5.17

jbarrez — Tue, 15 Sep 2015 10:32:25 GMT

There's but one way to know for sure and that is trying it …

I'm not aware of any specific fixes that went in around the issue described here (as we could not reproduce it), but of course many things have changed in the code so it always could be it is fixed for you.
