HTTPS 证书链不完整导致 unable to get local issuer certificate 排查

给公司部署 HTTPS 服务，证书来自内部 CA 体系（**Root CA → 中间 CA → 服务器 leaf 证书** 三级），客户端明明**信任了根证书**，访问时却报：

证书链不完整缺少中间证书unable to get local issuer certificate

JVM 堆外内存泄漏：Heap 很小 RSS 却暴涨被 OOM Killer 杀掉（exit 137）

一个 Java 图片处理服务跑在 1GB 内存的容器里，每天会神秘重启一次，`docker inspect` 看到退出码是 **137**（被 SIGKILL，通常是内核 OOM Killer 干的）。

RabbitMQ 消息堆积：未确认(Unacked)消息与队列积压导致内存告警 —— prefetch(QoS) 配置

一个数据处理系统通过 RabbitMQ 做异步削峰。生产者持续往队列 `task.queue` 投递任务，消费者取消息做耗时处理。某天发现：

Go TCP 粘包/半包问题详解：长度前缀分帧（length-prefixed framing）的正确实现

开发一个基于 TCP 的 Go 自定义协议服务，协议规定每条消息 = `[4字节大端长度][payload]`。服务端上线后收到的消息大量错乱：**粘包**（多条独立消息被合并成一条处理）、**半包**（一条完整消息被拆成多段分别处理）。日志中长度前缀字节（`\x00\x00\x00\x05`）混进了"消息正文

Nginx+PHP 上传 413：client_max_body_size 与 upload_max_filesize

Nginx + PHP-FPM 的 Web 应用支持用户上传文件，但**上传超过 1MB 的文件总是失败**，返回 **413 Request Entity Too Large**。小文件（<1MB）正常。检查服务器磁盘空间充足、Nginx/PHP 运行正常，日志里也没有 PHP 报错——因为请求根本到不了 PHP

Python 单线程阻塞式 TCP 服务器并发缺陷：Slowloris 式卡死与 selectors 修复

写 TCP 服务端时常见的一个坑：使用「单线程 + 阻塞 recv」结构，看起来能收能回，但**一旦有客户端连上却不发送数据，整个服务器就被卡死在 recv 上**，再也无法 accept 新的连接。
