  • Tomcat 启动报日志:

There is insufficient memory for the Java Runtime Environment to continue.

 

 

内存不够用了!。?,可是,那可是31个G呀~

  • free -h 查看内存使用情况:

 

可用内存仅剩305M

分析是tomcat项目启动太多

  • ps -ef |grep tomcat 查看Tomcat相关进程:

 

可以看到,Tomcat仍有多个进程在运行。

Solution

手动kill对应的pid,再次 free -h 查看内存使用情况:

 

可用内存瞬间恢复,尝试启动Tomcat,成功~
