I have a recurring error in my search crawl that I'm having trouble pinning down.
The error reads:
"http://portal.domain.comhttp://portal.domain.com/sites/sitename/_layouts/userdisp.apsx?ID=
The Content Plugin received a "Format Error" response from the backend server for the item.
( Expecting port in URL as number[0])"
As you can see the root url is duplicated somehow, and this error seems to scroll through for every user ID.
There is a redirect at the root site point to a new site under the "sites" managed path.
I have tried excluding the url path for crawls, but it hasn't made a difference.
