htaccess“此页面有太多重定向”重定向循环错误

I have searched across stackoverflow, since my problem is specific, couldnt find anywhere, so posting it here. Hope one of us can suggest the resolution. This is my htaccess code:

<IfModule mod_rewrite.c>
 RewriteEngine On
 RewriteBase /
 RewriteRule ^index\.php$ - [L]
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteCond %{REQUEST_FILENAME} !-d
 RewriteRule . /index.php [L]
</IfModule>

I'm getting the following error in chrome:

"this page has too many redirects " Redirect loop Error.

This happens often which means not everytime, but more often. Can anyone tell me whats the issue with above htaccess code?

Thanks.
