**What you expected to happen**:
相关代码：
// Invoke call remoting.
func (di *DubboInvoker) Invoke(ctx context.Context, invocation
protocol.Invocation) protocol.Result {
var (
err error
result protocol.RPCResult
)
if di.reqNum < 0 {
// Generally, the case will not happen, because the invoker has
been removed
// from the invoker list before destroy,so no new request will
enter the destroyed invoker
logger.Warnf("this dubboInvoker is destroyed")
result.Err = ErrDestroyedInvoker
return &result
}
atomic.AddInt64(&(di.reqNum), 1)
defer atomic.AddInt64(&(di.reqNum), -1)
竞态点：协程53使用原子写di.reqNum
协程1137未使用原子读di.reqNum
