   看panic堆栈比较明显。这是因为在dubbo-getty connection.go的SetWriteTimeout()中使用了uber atomic.Store, 在Store中会对val转换int64，导致在32位操作系统panic. 
   ```
   go.uber.org/atomic.(*Int64).Store(...)
           /StreamPlugins/gopath/pkg/mod/go.uber.org/atomic@v1.9.0/int64.go:75
   go.uber.org/atomic.(*Duration).Store(...)
           /StreamPlugins/gopath/pkg/mod/go.uber.org/atomic@v1.9.0/duration.go:55
   github.com/apache/dubbo-getty.(*gettyConn).SetWriteTimeout(0x4572080, 0x3b9aca00)
   ```
   
   ```
   func (x *Duration) Store(val time.Duration) {
   	x.v.Store(int64(val))
   }
   ```
