查看原因：
$ free -m
14:11:19 total used free shared buff/cache available
14:11:19 Mem: 7966 75 324 6 7566 7546
14:11:19 Swap: 1021 3 1018
发现剩下能用的内存太少，用下面方法解决：
sync
sudo su
echo 3 > /proc/sys/vm/drop_caches
查看结果如下：
free -m
14:39:11 total used free shared buff/cache available
14:39:11 Mem: 7966 76 7824 6 64 7705

为什么内存剩下这么少呢? 一开始git clone时连接中断报错，占用了cache没有释放。而我的git仓库大小是8G，cache直接就到了8G，所以内存一次就耗尽了。
