    random blank pages

    Seems my site is getting random blank pages. I did some research and maybe but not sure its related to open files.

    [[email protected] ~]# cat /proc/sys/fs/file-nr
    3264 0 900000

    Is this something to worry about? I just did a reboot and it did it.

    It should be a problem with high database access. You server requires apache and mysql optimization.

    Do check if your server is under any sort of DOS or DDOS attacks.. If not, then analyze the traffic during peak hours to tune your Apache/MySQL servers

    Are you having problems just with php files or html files too ?

    As with all things Apache, take a look at your error logs first. They can be in quite a few different places depending on the distro and the way apache is installed. Also you should verify wether it's a fully blank page, or if it's just not serving anything (big difference here).

    Is this something you can replicate fairly easily, or is it just random? However I think your first place to start should be correlating the times when a blank page is served with the same approx. time in your error logs. That should be the first place to start.

    Smart Person. I found there was a missing index on a very large table that contains all the IP addresses of visitors.

    I added the index and presto the problem stopped. But it didn't improve linux server load. But seems to not show blank pages now.

    Enable slow query logs ..check which of your DB have the issues ...
    And be sure to have the correct values in .my.cnf
