CCEngine can not start CCTask

We use ContextCapture Update 16 - v10.16.0.75 to run the RasterProduction TileProduction in a command line. Sometimes the server running CCEngine will be shutdown and reboot, then the command line, which will start the ccengine, will run antomatically after the server reboots. But without login, the CCEngine cannot start CCTask and be stuck for a long time. The log will be like this:

 .

The last log is: "Press enter to continue >".

Can anyone encounter this bug? or how can we handle this problem?
