sofa调用brpc请求过不来

[namelij]

Describe the bug (描述bug) 目前我们在做rpc框架升级，现有线上用的是百度的sofa-pbrpc，准备升级到brpc 为了保证稳定升级，目前挨个服务升级 比如流量从A->B->C，其中A B C都是微服务，且现有都是基于sofa框架实现 在升级过程中，A B不变，仍然是sofa框架，C使用brpc框架

自测过程中，发现升级成brpc后的C服务接收不到rpc请求(如果使用http直接请求C则可以，通过A B请求C则不可行)

通过status接口，信息如下： HTTP/1.1 200 OK Content-Length: 520 Content-Type: text/plain

version:xxx non_service_error: 1184 connection_count: 22 max_concurrency: unlimited [xxx]

Load (LoadRequest) returns (LoadResponse) count: 0 qps: 0 error: 0 eps: 0 latency: 0 latency_50: 0 latency_90: 0 latency_99: 0 latency_999: 0 latency_9999: 0 max_latency: 0 concurrency: 0

Update (UpdateRequest) returns (UpdateResponse) count: 0 qps: 0 error: 0 eps: 0 latency: 0 latency_50: 0 latency_90: 0 latency_99: 0 latency_999: 0 latency_9999: 0 max_latency: 0 concurrency: 0

PS: 通过brpc加log， 在ProcessSofaRequest函数中 有如下输出Fail to find method= sofa.pbrpc.builtin.BuiltinService.Health

疑问：sofa作为client，去请求brpc server，为什么会在server中检测sofa的Health函数呢

现有提供的信息没太看出什么问题，有其他的错误日志吗？最好是可以提供一个可复现的demo（比如一个简单的echo服务），比较好定位问题

感谢回复，我尝试在brpc中增加LOG，输出了Fail to find method= sofa.pbrpc.builtin.BuiltinService.Health

所以，根据上述推论，大致猜测是因为 client端的 sofa框架健康监测失败导致不下发流量过来
