STRANGE Error messages in System > Log, Please Help

Please help me in understanding the cause of these errors

also getting a lot of       ' Length cannot be less than zero. Parameter name: length    '


Log type:   Unknown

Severity:   11

Message:   Length cannot be less than zero. Parameter name: length

Exception:   System.ArgumentOutOfRangeException: Length cannot be less than zero.

Open the Google Webmasters pages. There should be a link called Diagnose with a submenu option Crawl Errors (names might be different, since I'm looking at it in Dutch).

If everything is OK, the only pages that are in the list(s) are pages that are blocked by the robots.txt file.
All other errors should be displayed there, if any.

in HTTP

there are no errors

but when i click on Restricted by robots.txt

it gives me following url there were not in the system log errors

i see these :

www.mywebsite.com/Account.aspx
www.mywebsite.com/CompareProducts.aspx
www.mywebsite.com/Login.aspx
www.mywebsite.com/Wishlist.aspx

strange cuz i never got any error in system > log related to these pages

and these pages are working perfectly fine

and what about the blog page error that i am getting ?

(I posted those blog errors on this thread, in page 1, last post)

Same errors here, on 1.5 deployment.

- Padding is invalid and cannot be removed.

- This is an invalid script resource request.

There were 14 entries over the course of 35 minutes. Is this capturing some type of security event? Anyone have any idea what they are?

Numerous IP addresses.

i am on 1.4 version

Darrell, you posted your website sitemap on google webmaster ?

Yes. I posted on Google, Yahoo and Bing through the webmaster tools. But, I only posted the URL, I did not explicitly post a site-map.

I have left the robots.txt as the nop default.

I also ran a short ad-word campaign on Google and On-Line Marketing on Yahoo.

Also, posted my link here on the show-off forum.

the reason i asked - everyone who is having this issue of getting strange errors in system log, i guess we all have one thing in common, we have posted our website on Google Webmaster, and i guess Google crawler is throwing these error messages while crawling on website pages
