nonce unquienesss constraint #289
Description
when the system restarts the database can get into an error state if a previously used execution set is sent to the database from the manager the database can get into an error state where it rejects due to a duplicate correlator nonce.
When the database is in this error the manager continues to attempts to connect cause it to reach an error state.
Restarting the database and manager is a currently the only fix.
Would need to update the SP or database table constraint for execution set to handle duplicate nonces.
And also improve manager error handling when the database is on reachable.
