启动tomcat抛出异常
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 552599552 bytes for committing reserved memory.
# An error report file with more information is saved as:
# /TRS/HyCloud/IIP/hs_err_pid5871.log
解决
查看内存->使用14G
查看端口占用->无应用
查看java进程
果然：停止tomcat日志一直未停掉
使用命令:
kill
