今天，中午2：40网站突然挂掉，怎么都打不开，重启apache、甚至服务器都不管用！陆陆续续搞了两个小时，最后查了查apache的 error_log 文件，没发现什么异常日志记录，但却有很多类似的记录：
[[email protected] logs]#tail error_log
......
[[email protected] logs]# tail error_log
[Thu Nov 05 16:35:29 2009] [notice] child pid 8811 exit signal File size limit exceeded (25)
[Thu Nov 05 16:35:29 2009] [notice] child pid 8812 exit signal File size limit exceeded (25)
[Thu Nov 05 16:35:29 2009] [notice] child pid 8813 exit signal File size limit exceeded (25)
[Thu Nov 05 16:35:30 2009] [notice] child pid 8814 exit signal File size limit exceeded (25)
[Thu Nov 05 16:35:30 2009] [notice] child pid 8815 exit signal File size limit exceeded (25)
[Thu Nov 05 16:35:31 2009] [notice] child pid 8807 exit signal File size limit exceeded (25)
[Thu Nov 05 16:35:31 2009] [notice] child pid 8816 exit signal File size limit exceeded (25)
[Thu Nov 05 16:35:32 2009] [notice] child pid 8788 exit signal File size limit exceeded (25)
[Thu Nov 05 16:35:32 2009] [notice] child pid 8790 exit signal File size limit exceeded (25)
[Thu Nov 05 16:35:32 2009] [notice] child pid 8817 exit signal File size limit exceeded (25)
到google里搜索，发现了问题的所在：
上面的错误记录是说有文件大小超过了限制（超过了apache 2G的文件限制）试用find命令在系统里面查找超大的文件
[[email protected] logs]# find / -size +1000000k
find: /proc/9540/task/9540/fd/4: No such file or directory
find: /proc/9540/fd/4: No such file or directory
/xxxxxxx/xxxxx/logs/php_error.log
再查查php_error.log的实际大小
[[email protected] /]# ls -al /xxxxxxx/xxxxx/logs/php_error.log
-rw-r--r--1root 4294967295 21474836477月 10 06:14 /xxxxxxx/xxxxx/logs/php_error.log
我靠！！！ 这 php_error.log 文件这么大呀！
把这文件压缩备份后,删除,然后再重新启动apache[[email protected] /]# /usr/local/apache/bin/apachectl restart
搞定了！瞎折腾了这么久
