MOSS 2007, error 6482 repeating every 30 seconds

When I look in the application logs for the machine that's running MOSS 2007 I can see the following error:

Type: error
Source: office server shared services
Event: 6482
User: N/A

This error is being logged every 30 seconds since at least a couple of weeks back and I can't get it to stop. I've tried googling for error 6482 but I haven't found a solution for it.

The server is running windows 2003 R2 Standard Ed. (with SP2),MS SQL 2005 (think it's Enterprise, im 100% sure its not Express version anyway) and MOSS 2007.

Anyway, the full info when opening one of the errors is the following:

"Application Server Administration job failed for service instance Microsoft.Office.Server.Search.Administration.SearchAdminSharedWebServiceInstance (0df54aa0-a97a-42b5-9d3e-b875cfce3986).

I would really appreciate some help on how to get rid of this annoying error. I haven't made any changes on this server for a long time, the error just suddenly appeared out of nowhere.

Any suggestions on what I should try to remedy this?

Thanks
