biedongbin opened a new issue, #7986: URL: https://github.com/apache/incubator-seata/issues/7986
### Check Ahead - [x] I have searched the [issues](https://github.com/seata/seata/issues) of this repository and believe that this is not a duplicate. - [ ] I am willing to try to fix this bug myself. ### Ⅰ. Issue Description 因seata-server 配置了读写分离的数据库配置 引起了事务问题，因此 修改了配置之后重启sea-server 版本 ：2.5.0 注册中心：nacos 环境：生产环境 部署形式：阿里云K8S集群 docker 内 seata-server.jar ### Ⅱ. Describe what happened 重启之前一切正常，事务正常，链接正常，因读写分离问题，偶发 事务注册之后、再次注册分支事务或者分支事务上报会出现异常， 检查了所有的配置项，未发现有关 心跳检测相关内容。 重启之后 客户端一直在异常， 最后没办法 重启了客户端应用后正常。 `2026-02-04 18:49:58,512 [NettyClientSelector_TMROLE_1_2_4] INFO [] [] [o.a.s.core.rpc.netty.AbstractNettyRemotingClient] - ChannelHandlerContext(AbstractNettyRemotingClient$ClientHandler#0, [id: 0x44dd1c62, L:null !
