Cron Job Problem

Hope someone help me with this problem:

I start receiving this email: 

<h4>An error occured: </h4> <script> top.location = 'index.php?op=config&errmsg=%3Cb%3EThere+was+an+error+while+retrieving+the+URL+specified%3A%3C%2Fb%3E+http%3A%2F%2Finim.com%2F%3Cbr%3E%3Cb%3EHTTP+headers+follow%3A%3C%2Fb%3E%3Cbr%3E%3Cbr%3E%3Cb%3EHTTP+output%3A%3C%2Fb%3E%3Cbr%3E' </script> 

Any idea what this can be?

Thanks

also this other email there is related to the cron job:

<div style="border:2px solid red;padding:4px;width:600px;margin:0px auto;"> <div style="text-align:center;background-color:red;color:white;font-weight:bold;">Error</div> <div style="text-align:center;">Database connect failed</div> </div> Fatal error: Call to a member function getParam() on a non-object in /home/wwwinim/public_html/inc/db.inc.php on line 83

Check your cron job and for second error its a database connection error, it maybe temporary.
