Unexpected end of workflow

[mbogomilov]

Hello,

I have a workflow that contains a receive task. Once in that state, the workflow awaits for a signal to move into an end state. I have a process instance that ended without receiving that signal and its last state is the receive task. Are there any means to troubleshoot this by using the activiti tables? I checked in act_hi_actinst and I can see the last transition was to the rececive task and that there is an END_TIME_ value of that but I don't know how to find out what happened after receive task ended - why the end state was not reached. Searching in the RU* tables I can't find any trace of that instance and an attempt to resume the workflow returns an error (ProcessInstance not found).

If it helps, this is what the incomplete workflow looks like:

mysql> select ACT_ID_,ACT_NAME_,ACT_TYPE_,START_TIME_,END_TIME_,DURATION_ from act_hi_actinst where PROC_INST_ID_='cd4df260-1693-11e6-b480-5254007475b8' order by START_TIME_ asc;
+——————-+——————-+——————+———————+———————+———–+
| ACT_ID_           | ACT_NAME_         | ACT_TYPE_        | START_TIME_         | END_TIME_           | DURATION_ |
+——————-+——————-+——————+———————+———————+———–+
| pushGateway       | Exclusive Gateway | exclusiveGateway | 2016-05-10 02:44:34 | 2016-05-10 02:44:34 |         1 |
| startRunOrder     | Start             | startEvent       | 2016-05-10 02:44:34 | 2016-05-10 02:44:34 |         1 |

| activationGateway | Exclusive Gateway | exclusiveGateway | 2016-05-10 23:30:28 | 2016-05-10 23:30:28 |        12 |

And this is a complete workflow:

is this happen in your production environment?
Can you receate the scenario?

[mbogomilov]

No production yet but soon. I just saw this error today once.

[faizal-manan]

need to recreate the scenario

Hi mbogomilov

Can you reproduce the issue in the jUnit test?

If I could reproduce it with a test I could probably find the root cause as well. If/when it happens again I'll make sure I collect meaningful data around the event so we can hopefully become able to troubleshoot this.
