FB wall posting OAuthException

i have integrated the fe开发者_运维百科ed post PHP-SDK by using the following set of codes

$attachment =  array(
    'access_token' => $accestoken,
    'message' => "Favorite Restaurant is ".$business['name'].$business['location']['city']."-What is yours? ",
    'name' => $business['name'],
    'link' => $business['personal_url'],
    'description' => "<b>myTaste || real restaurant reviews, share your taste on myTaste</b>",
    'picture'=> "http://mysite.com/images/gui/header/mytaste.gif"
);  
$facebook->api("/".$usid."/feed", "post",$attachment);  

Everything worked great for one day, but today it was showing the following error codes.

Uncaught OAuthException: (#341) Feed action request limit reached thrown in /hsphere/local/home/mysite.com/include/3rdparty/facebook-php-sdk/src/facebook.php

Uncaught OAuthException: (#210) User not visible thrown in /hsphere/local/home/mysite.com/include/3rdparty/facebook-php-sdk/src/facebook.php

Your application seems to have reached the limits of interaction.

1. Login to facebook
2. Visit http://www.facebook.com/insights/
3. Select your App
4. Click on API
5. Look for API Throttling tab.

And see what limits your have reached.

To find out how to fix this and what exactly causes this you can read more about it in these threads on Facebook's developer forum:
