Solution:

Errant tasks such as this can be deleted from the system through the use of the RepositoryDriver.exe. If this tool is not used with care, then data loss could result.

Before proceeding, it is strongly recommended to:

  1. Complete all tasks.
  2. Backup the database.

In C:\Program Files\GeoCue\GeoCue Server there is a utility called RepositoryDriver.exe.

Right-click on the RepositoryDriver.exe, and select “Run as Administrator”.
