What does your actual view markup look like? I am surprised to see an `Object state` exception in an MVC application — Tommy, Jan 23 '14 at 05:29

Looks like you are doing DoS attack on yourself. I think that you have 2 options:

alter web config(ref. http://geekswithblogs.net/renso/archive/2012/01/19/operation-is-not-valid-due-to-the-current-state-of.aspx):
```
<appSettings>
<add key="aspnet:MaxHttpCollectionKeys" value="2000" /></appSettings>
```
dont post whole form, just the part with data you need(carriers to be added). Either using jquery, or adding only fields to be posted inside form tag.
