根因分析
Lambda SnapStart 初始化钩子（例如 Java）在快照创建期间超过了 10 秒限制。
English
Lambda SnapStart initialization hook (e.g., for Java) exceeded the 10-second limit during snapshot creation.

-
优化 `CRaC` 或 `beforeCheckpoint` 钩子中的初始化代码：将重负载设置（如数据库连接池）移至检查点后的延迟初始化。
-
使用更小的运行时或减少类路径扫描：在 Spring Boot 中设置 `spring.context.initializer.exclude` 以跳过慢速 bean。
无效尝试
常见但无效的做法:
-
100% 失败
Increasing Lambda timeout setting doesn't affect SnapStart hook timeout; the 10-second limit is fixed.
-
50% 失败
Disabling SnapStart entirely removes the performance benefit and doesn't fix the root cause.
