[求助] 403 錯誤緊急求助

wpcp0510

網(wǎng)頁以前挺正常，最近莫名其妙的出現(xiàn)403錯誤，提示如下：
Forbidden
You don't have permission to access / on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

遇到這種錯誤刷新頁面偶爾會恢復，最終需要service httpd restart 重啟下才能正常訪問。
但是可能過10幾個小時錯誤又會重新出現(xiàn)，重啟httpd服務(wù)就好。

看日志有這種提示：
(24)Too many open files: /www/web/public_html/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable, referer:
根據(jù)百度搜索說要修改文件夾權(quán)限為755，但是查詢文件夾權(quán)限沒錯。

請教是什么原因?qū)е碌�？如何辦？

Google搜到一個：

1) A simple restart of apache fixed it all of a sudden.

2) Try ulimit -a as root and  check for “open files”. The default value will be 1024. Try raising it to 4096 as follows.

ulimit -n 4096

3) Also, you can raise this limit for apache by giving it in apache startup script at the beginning.

vi /etc/rc.d/init.d/httpd

Enter the following line at the beginning of the script.
ulimit -n 65536

Save the file and restart apache

/etc/rc.d/init.d/httpd restart
