ERROR: The Scheduler cannot be restarted after shutdown() has been called.

One of the pipelines that we created immediately switces to "FINISHED" state after we start it. This started happening after we "FORCE SHUTDOWN " the pipeline with the CRON. Looks like the Pipeline id got registered somwhere with the CRON Shutdown status and wont allow us to restart.

Restart of the server fixed it, it was primarily because a force shutdown of CRON pipeline sends it to shutdown status in the repository/databse(not sure where) and any new restart of the pipeline finishes immediately with the mentioned error.
