Tracking down an Umbraco Error Message

I have a couple of packages installed in my Umbraco installation so it would be kinda hard to to track down each one of them on开发者_开发技巧e by one. I get this error message every 5 minutes in the log file:

Error executing scheduled task: System.UriFormatException: Invalid URI: The hostname could not be parsed. at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind) at System.Net.WebRequest.Create(String requestUriString) at umbraco.presentation.publishingService.getTaskByHttp(String url) at umbraco.presentation.publishingService.CheckPublishing(Object sender) 

Is there a faster way of tracking down the issue?

The issue is caused by the built-in task scheduler. Have a look in the config\umbracoSettings.config file and find the scheduledTasks node. There you'll find something that is supposed to run every five minutes and has a wrong URL specified.
