The form submission cannot be processed because it exceeded the maximum length allowed by the Web.

Reason:

Whenever you are trying to upload a file into the SharePoint with more than 50MB, you will get this error. 

You can not fix this issues, even if you updated the tag in web.config file.

Solution:

1. Go to Central Admin

2. Open "Web Application Gegenal settings" link

3. There is an option to enter the maximum file size. type 100 MB in that text box. Don't forget to change the web application in the dropdown box.

4. Also, change the HttpRuntime in the web.config as follows:

 <httpruntime maxrequestlength="102400" executiontimeout="3600"></httpruntime>

 

Thats it...
