The log shows that tikv is too busy, often caused by conservative configuration or weak hardware performance.

@c4pt0r My test machine is four 8-Core 16G-Memory machine.I'm doing a test. Maybe the hardware is not enough,the tikv-server cpu is up to 80% when normal running, I try to set the mysql timeout time or add new machine to cluster.
