How does pyspider kill duplicate queues in scheduler

Click RUN on the

console and report this
[E 180704 09:49:46 scheduler:1223] 1062 (23000): Duplicate entry "on_start" for key" PRIMARY"

).

mysql.connector.errors.IntegrityError: 1062 (23000): Duplicate entry "on_start" for key" PRIMARY"

)

normally running tasks are in this queue, so I wonder if we should kill 1223 of the queue first, and I can"t restart
[I 180704 09:53:53 scheduler:586] in 5m: new:0,success:0,retry:3,failed:0 baixing:0,0,3,0
