服务注册失败重试问题

[freelingchang]

前些天我们的zookeeper 有个节点(应用只配置了一个节点)卡了1分钟左右，导致小部分服务状态丢失，当zk恢复正常后服务并没有重新注册去，请问怎么调整注册(非调用)重试时间间隔和总次数?谢谢~

以下是provider日志信息

后面一直重复

遇到过相同的问题，后来有什么解决方案吗？ @freelingchang

I am afraid currently Dubbo does not support retry on service registration. I think this can be an improvement.

现在应该没有这个问题，你试试最新版本。
