调查：

通过top -b >> /tmp/1.txt

发现是swap内存被消耗光了，原来的2G swap 不够

解决：

通过文件方式扩大swap分解的大小

创建要作为swap分区的文件：

root 用户登陆

touch/home/swapfile

dd if=/dev/zero of=/home/swapfile bs=1M count=8192

格式化为交换分区文件:

[root@hzNgJenkins home]# mkswap /home/swapfile
Setting up swapspace version 1,size = 8388604 KiB
no label,UUID=8556066c-dbed-4a26-941b-aab2e0a51a76
[root@hzNgJenkins home]#

#启用交换分区文件

chmod 0600 /home/swapfile

swapon /home/swapfile

# free -m 查看结果

#系统开机自启动：

在文件/etc/fstab中添加一行：

/home/swapfile swap swap defaults 0 0
