我在4G内存上运行Postgresql 9.2，Atom N2800 CPU Windows POS READY嵌入式系统（如XP）机器，基本上它在生产环境中运行良好多年，但崩溃了（服务停止了）经常在最近的表现（ not stress ）测试。
我认为测试没有太大的压力，启用了log_min_duration_statement = 0，下面列出了测试内容的简化总体统计数据：
说20分钟是一个度量单位，所以在一个单位：
5000次更新，每个查询包含20KB大小的数据（包含Text字段）。
35000次 SELECT ，每个查询返回20KB大小的数据（获取Text字段）。
在崩溃之前，日志没有看到任何异常并留下这个：

我可以指出的一件事是shared_buffers的数据库配置，现在设置为256MB，它就是没有任何理由，是否有助于增加此值？
其他主要设置：max_connections=200，temp_buffers = 16MB，work_mem = 8MB
任何人都可以帮助检查崩溃的发生方式，或者如何最小化范围？
答案 0 :(得分：0)
0xC0000142STATUS_DLL_INIT_FAILED- {DLL初始化失败}动态链接库％hs的初始化失败。该过程异常终止。
所以这是一个DLL加载问题和/或启动新进程的问题。如果我不得不猜测我说你的XP Embedded系统上的打开文件数，运行进程数等可能会受到限制。您可能希望降低max_connections。
