我发现如果注册中心是 nacos ，在 32 位的 armv7 上运行的 dubbo-go(v3.0.1) cilent 启动后就会崩溃。如果将注册中心改成 zookeeper，cilent 就不会崩溃。目前的解决方法是使用 zookeeper 作为注册中心。 @LaurenceLiZhixin

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))
}
```
