求助贴： Centos 经常 OOM 是怎么回事？

大体配置如下：

➜ ~ # free -lmh

Mem: 1.0G 639M 366M 30M 187M 184M
Low: 868M 501M 366M
High: 138M 137M 252K
-/+ buffers/cache: 267M 739M
Swap: 2.0G 0B 2.0G

➜ ~ $ uname -ri
2.6.32-642.1.1.el6.i686 i386

➜ ~ $ cat /etc/centos-release
CentOS release 6.8 (Final)

请问如何正确配置才能避免 OOM 的出现？还是说内存已经就是瓶颈，再怎么优化配置没有用？
