现象:部署完项目打开浏览器访问的时候报404的错误。

定位:清空浏览器的缓存

     查看tomcat的运行状况

     打开log查看

结果:在log日志中发现如下(部署了三次)

 1 Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000005c0000000, 8589934592, 0) failed; error=Cannot allocate memory (errno=12)

 3 # There is insufficient memory for the Java Runtime Environment to continue.
 4 # Native memory allocation (mmap) failed to map 8589934592 bytes for committing reserved memory.
