Much Ado About Nothing (404 caused exeptions)

[WWWestern 94]

MBS v. 3.0.5083.27698

When gets 404 error, stops libraty scan for few minutes, even ten . Actually offending source is http://www.thetvdb.com/banners/seasonswide/79708-1.jpg and it is S01 banner for The Sarah Jane Adventures. Although the API provides a link to the image, it is missing on the site. I cheated the MBS, slipping fake banner to season folder. After that the scan is ended now within seconds.

Why so much time it take to process this particular event? Is it possible to reduce this pile of messages and let the squad goes on.
