Synchronisation fails with error: "[1779007] Cannot start full sync because the same full sync is still running."

A full synchronization goes into a FROZEN state with the following error:

"[2134003] Error executing a full projection!
[1779007] Cannot start full sync (Initial Synchronization) because the same full sync is still running.

DPRProjectionStartInfo.LastStart is still set from the last synchronisation job.

With Object Browser, clear the current value for DPRProjectionStartInfo.LastStart for the given configuration.

One may also use the "Reset" button on the "Start up configurations" tab for the sync project.
