Error 508 when running SmartCrawl SEO Scan

When running SmartCrawl I get the following message on in the progress bar http://www.pastefile.com/zQdRIJ
So if I try to navigate to another page I get error 508 Resource Limit is Reached and I have to wait some time so I can access the front end or WP Admin area of my site.

Thanks in advance.
