根因分析
同一通道上注册了太多并发连接状态监视,超过了内部限制。
English
Too many concurrent connectivity watches were registered on the same channel, exceeding the internal limit.
官方文档
https://grpc.io/docs/guides/performance/解决方案
-
Limit the number of concurrent watches per channel. In C++, use `channel->GetState(true)` instead of multiple `NotifyOnStateChange` calls.
-
Increase the limit via `GRPC_ARG_MAX_PENDING_WATCHES` (if available) or use a separate channel per watch group.
无效尝试
常见但无效的做法:
-
50% 失败
The limit is per channel; creating more channels may exhaust other resources.
-
70% 失败
This reduces the timeout but does not prevent the limit from being hit.
-
80% 失败
The watch failure may cause missed connectivity changes, leading to RPC failures.
