Human task escalation ERROR

Question

Hi,
I have a BPEL process with a human task. This human task has set the expiration time and the escalation policy (2 escalation steps).
The BPEL works alright if nobody does nothing to the task. It fails if the task is claimed by a user but after the user doesn't finish the task (doesn't take any actions on the task, neither approve/reject)
The task is expired and the status is "with errors". In the logs the following error appears:
<2008-06-25 16:08:40,093> <ERROR> <oracle.bpel.services.workflow> <::> ORA-20003: Error while inserting routing slip

Hi Charles,
First of all thank you for the reply.
Right now I'm working in a development environment, where we don't have a cluster. In production environment we do have a cluster for the soa suite so it would be good to know the patch for the cluster.
On the other hand, I upgraded from 10.1.3.1 to 10.1.3.3 but I didn't run the database script. After reading this post, I executed the upgrade_10131_10133_oracle.sql script but I'm getting the same error.
One thing that I don't understand is that the log says:
java.sql.SQLException: ORA-20003: Error while inserting routing slip
ORA-06512: en "ORABPEL.WFTASKPKG", línea 47
ORA-00001: restricción única (ORABPEL.SYS_C005188) violada
ORA-06512: en línea 1
I connect to the database using orabpel user and I don't find the WFTASKPKG table. Is this normal? What is going on?
Also, the escalation works alright if no user claims the task.... so I guess it is not an LDAP configuration issue. (both users exist and have title and manager set up)
