> Leader server enters into deadlock while shutting down. This happens some time only.
> The reason and deadlock flow is same as ZOOKEEPER-2380.
> shutdown was removed from synchronized block in ZOOKEEPER-2380
> Now shutdown is called from synchronized block from another place.
> {code}
> // check leader running status
> if (!this.isRunning()) {
>     shutdown("Unexpected internal error");
>     return;
> }
> {code}
