环境：CentOS6.7 + Apache2.4 + Django1.8

背景：早前对apache日志按天进行了分割，每天日志文件大小很稳定。最近发现apache错误日志文件巨大，每天都打印很多很多行\[wsgi:error\]

[Mon Dec 26 08:24:58.245875 2016] [wsgi:error] [pid 24768:tid 140371390662400] 17

    [Mon Dec 26 08:24:58.246046 2016] [wsgi:error] [pid 24768:tid 140371390662400] 6
    [Mon Dec 26 08:24:58.246061 2016] [wsgi:error] [pid 24768:tid 140371390662400] 5

观察了很久，发现每一行错误日志最后的内容都是项目中打印的字段，网上查了很久，最终发现这些wsgi:error是Django代码中的print语句引起的，注释掉所有的print语句后问题解决。
