这个日志报错涉及到了多个错误消息，主要集中在 RPC 调用失败上，具体分析如下：

错误分析

RPC 连接错误

错误消息 "rpc error: code = Unavailable desc = last connection error: connection error: desc = \"error reading server preface: read tcp 127.0.0.1:52240->127.0.0.1:7890: read: connection reset by peer\"" 指出了一个 RPC 连接问题。这个问题的根本原因是在尝试读取服务器的前言信息时，连接被对端重置。这种情况通常发生于以下几种情况：

服务器未准备好接受连接：服务器可能在重启中或者还未完全启动，导致尚未准备好接受连接。
网络问题：虽然这里的地址是本地回环地址（127.0.0.1），表明客户端和服务器在同一台机器上，但TCP连接仍然可能因为系统网络配置错误或资源限制而被重置。
服务器拒绝连接：服务器可能由于配置错误、资源限制（如文件描述符限制）或安全策略拒绝了连接。

错误代码和消息

日志中的错误代码为 14，这对应于 gRPC 的 UNAVAILABLE 状态，表明服务不可用。这通常是因为服务器无法正确处理来自客户端的请求。同时，错误详情包含了具体的连接错误描述，帮助开发者诊断问题。

解决方案建议

针对此类问题，可以尝试以下几种解决方案：

检查服务器状态：确保服务完全启动并且处于监听状态。可以使用工具如 netstat 或 ss 检查端口（如 7890）是否被正确监听。
检查服务日志：服务端的日志可能提供了为何连接被重置的更多信息。可能是由于启动失败、配置错误或其他内部错误导致服务不稳定或无法启动。
网络配置和资源限制：确认系统的网络配置正确无误，并检查是否有资源限制（如打开文件的最大数量）导致服务无法接受新的连接。
客户端和服务端版本兼容性：确保客户端和服务端使用的 gRPC 版本兼容，以及任何相关的中间件或代理兼容性。

如果问题持续存在，可能需要深入分析服务端的实现和配置，以及客户端的连接逻辑，从而找到根本原因并解决。在某些复杂的情况下，可能还需要利用网络抓包工具（如 Wireshark）来观察和分析 TCP 层面的通信细节。

This log error report involves multiple error messages, mainly focusing on RPC call failure. The specific analysis is as follows:

Error analysis

RPC connection error

Error message "rpc error: code = Unavailable desc = last connection error: connection error: desc = \"error reading server preface: read tcp 127.0.0.1:52240->127.0.0.1:7890: read: connection reset by peer\ "" indicates an RPC connection problem. The root cause of this issue is that the connection was reset by the peer while trying to read the server's preamble information. This situation usually occurs in the following situations:

Server is not ready to accept connections: The server may be restarting or has not fully started, causing it to not be ready to accept connections.
Network Issue: Although the address here is the local loopback address (127.0.0.1), indicating that the client and server are on the same machine, the TCP connection may still be reset due to system network configuration errors or resource limitations .
Server Rejected Connection: The server may have rejected the connection due to misconfiguration, resource constraints (such as file descriptor limits), or security policy.

Error codes and messages

The error code in the log is 14, which corresponds to gRPC's UNAVAILABLE status, indicating that the service is unavailable. This is usually because the server is unable to properly handle the request from the client. At the same time, the error details include specific connection error descriptions to help developers diagnose problems.

Solution suggestions

For this kind of problem, you can try the following solutions:

Check Server Status: Make sure the service is fully started and in listening state. You can use tools such as netstat or ss to check whether the port (such as 7890) is being listened to correctly.
Check service logs: Server-side logs may provide more information as to why the connection was reset. The service may be unstable or unable to start due to a startup failure, misconfiguration, or other internal error.
Network Configuration and Resource Limits: Verify that the system's network configuration is correct and check to see if there are any resource limits (such as the maximum number of open files) that prevent the service from accepting new connections.
Client and Server Version Compatibility: Ensure that the gRPC versions used by the client and server are compatible, as well as any related middleware or proxy compatibility.

If the problem persists, you may need to deeply analyze the implementation and configuration of the server and the connection logic of the client to find the root cause and solve it. In some complex cases, it may be necessary to use network packet capture tools (such as Wireshark) to observe and analyze the communication details at the TCP level.
