--------------------------------------------------------------
Hi,
I have been developing jBPM web application using jBPM 5.4 and with the tutorial from
http://www.mastertheboss.com/jbpm5/jbpm-5-on-jboss-as-7
http://www.mastertheboss.com/jbpm5/jbpm-5-on-jboss-as-7
I have configured to use mssql.
My Bpmn is very simple from START --- > TASK A ----> TASK B ----> STOP
Unfortunately, when one task is completed i get the following scenarios,
1. Only task is created as required but when i complete it it doesnt end.
i hope it stops with an exception, Error when creating task on task server for
work item id 170. Error reported by task server: Task operation request timed out:
java.lang.RuntimeException: Task operation request timed out
2. More than one task is created, i'm not sure which one must be proceeded with.
3. No task is created, with the following error, Error when creating task on task server
for work item id 170. Error reported by task server: Task operation request timed out:
java.lang.RuntimeException: Task operation request timed out
Why does it is not working deterministicly.
Can anyone pls help me.

Try with LocalTaskService(just to check if there is not other issue). Problem is time of
execution is more than default waiting time for HornetQHandler. You can use debugger and
see.
