Resolution

Stop the driver and delete the state files for the driver in the eDirectory DIB directory.   Be careful only to delete the state files, and nothing else.   The state files contain the GUID of the driver object as a name.  

Example of state file names:
jdbc_a9418efd-5fef-48a1-e6a7-fd8e41fa234a.t
jdbc_a9418efd-5fef-48a1-e6a7-fd8e41fa234a.p
jdbc_a9418efd-5fef-48a1-e6a7-fd8e41fa234a

Note:   DO NOT RENAME THE FILES!!!   They are still referenced if they are present in the directory.   Either delete them completely (they will be rebuilt upon driver startup) or move them completely off the server.

Cause

Corrupt triggerless state files.
