Users Loses His Demantra Worksheet Session While The Simulation Is Running (Doc ID 1103758.1)

Symptoms

Client executes a simulation but then is timed out of Demantra (session.expiration) before it completes and when they log back in they try to either cancel the simulation, but there is no record for it in the Process Monitor, or they try to re-simulate and they get the error message

ODPM-10284 Simulation table already exists in the database for the worksheet

There is no choice to accept or reject the simulation.

The error on the back end Collaborator.log is similar to:
