We have a webapplication that calls a web service residing in an EAP server.

And we have a workflow setup in BPMS6 on the same server. The web service triggers an action in the workflow.

We recently noticed that some of the action failed and the status of the task (based on the TASK table) were stuck in "InProgress" state.  We tried calling the action again but it fails and status remains InProgress.

We tried updating the status directly in the database to "Reserved" and call the webservice again, but it still failed and update the status back to "InProgress".  How do we make it to move to the next state in the workflow.

We got the following error messages in the logs:
