背景

早上在用IDEA构建项目的时候，爆出了以下问题。

OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x000001faf3e50000, 65536, 0) failed; error='页面文件太小，无法完成操作。' (DOS error/errno=1455)

根据log的内容分析，应该是内存撑不住，爆了。

我看了下我的操作，我发现因为我允许多项目启动。同时启动了多个服务和调试。

中间还有个XXL-job服务。我也是醉了。

所以导致项目内存不够了。

 

解决方案

那么很简单，直接把所有的项目stop掉，然后重新构建就可以了。

其实IDEA自带了Profiler窗口，你可以直接查看这个窗口就知道哪个占用了内存了。

总结

问题都会有的，关键是要稳住，不要慌，错误日志越多，定位问题就越简单。
