kitex [XDS] client, receive failed, error=connection error: desc = "transport is closing"

测试环境：istio，服务发现是用原生的istio 系统版本： k8s:版本：v1.25.4 istio版本：1.17.1 docker 20.10.23

遇到的问题： proxyless模式，pod运行一会后一直报 2023/03/20 08:11:43.723511 client.go:227: [Error] KITEX: [XDS] client, receive failed, error=connection error: desc = "transport is closing" 2023/03/20 08:42:20.372792 client.go:227: [Error] KITEX: [XDS] client, receive failed, error=connection error: desc = "transport is closing" 2023/03/20 09:15:12.557724 client.go:227: [Error] KITEX: [XDS] client, receive failed, error=connection error: desc = "transport is closing"

一直报？看你贴出来的日志是半小时左右一次。可以看一下istiod的日志，看看是否有错误日志。

只有几个warn，其它都ads的info 2023-03-20T09:21:56.030703Z warn model Istio Version is not found in metadata for api-useraccount-v1-6475fd8c4b-bltjl.mesh-cloud, which may have undesirable side effects

第一请求正确响应，第二次请求就500，过段时间再请求，又正确响应了，pod没有重启 500报如下错误 [Error] KITEX: processing request error, remoteService=, remoteAddr=10.9.0.18:50442, error=biz error: no matched route for service code.cloud.svc.cluster.local:8080, err=get route failed: [XDS] manager, fetch RouteConfig resource[code.cloud.svc.cluster.local:8080] timeout

能提供一下你请求的代码吗？

Mar 20 '23 11:03 ppzqh

func init() {
	if err := xdsmanager.Init(xdsmanager.WithXDSServerAddress("istiod.istio-system.svc:15010")); err != nil {
		panic(err)
	}
}

func InitVCodeClient() {
	var (
		destService string
		options     []client.Option
	)
	destService, options = k8sVCodeOption()

	var err error
	VCodeClient, err = vcodesrv.NewClient(
		destService,
		options...,
	)
	if err != nil {
		panic(err)
	}
}

func k8sVCodeOption() (string, []client.Option) {
	return "code.cloud.svc.cluster.local:8080", []client.Option{
		client.WithSuite(tracing.NewClientSuite()), // tracer
		client.WithXDSSuite(xds.ClientSuite{
			RouterMiddleware: xdssuite.NewXDSRouterMiddleware(
				xdssuite.WithRouterMetaExtractor(metadata.ExtractFromPropagator),
			),
			Resolver: xdssuite.NewXDSResolver(),
		}),
	}
}

请问是否有配置destinationRule？

istio server设置了默认连接空闲时间是30分钟，如果这段时间内没有xds推送，那么连接就会被istio关闭了。

你好，这个问题最终是怎么解决的呢，是需要配置哪个配置参数？
