Linux启动jmeter OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c0000000, 1073741824, 0) failed; error='Cannot allocate memory' (errno=12)

在Linux上安装jdk、jmeter配置好环境后。启动jemter的时候报错。

[root@iZwz9bpj7oo7xbrms4f83hZ ~]# jmeter -v
OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c0000000, 1073741824, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 1073741824 bytes for committing reserved memory.
# An error report file with more information is saved as:
# /root/hs_err_pid14234.log
[root@iZwz9bpj7oo7xbrms4f83hZ ~]# 

以上报错是因为服务器内存不足，无法启动所导致。

自查：

　　1、输入free-m，查看可用内存。

[root@iZwz9bpj7oo7xbrms4f83hZ ~]# free -m
              total        used        free      shared  buff/cache   available
Mem:           1734         967          87           0         679         583
Swap:             0           0           0

　　2、查看已启动的服务，停掉部分已启动的进程。（docker部署示例）

[root@iZwz9bpj7oo7xbrms4f83hZ ~]# docker ps
CONTAINER ID   IMAGE                     COMMAND                  CREATED        STATUS         PORTS                               NAMES

　　停掉一个服务

[root@iZwz9bpj7oo7xbrms4f83hZ ~]# docker stop 67d3f0472ceb 8bd33f9f9e01
67d3f0472ceb
8bd33f9f9e01

　　3、再查看内存空间

[root@iZwz9bpj7oo7xbrms4f83hZ ~]# free -m
              total        used        free      shared  buff/cache   available
Mem:           1734         557         467           0         710         996
Swap:             0           0           0

　　4、再启动jmeter

[root@iZwz9bpj7oo7xbrms4f83hZ ~]# jmeter -v
