Comment(by Emil):

 We had this issue too, resulting in image uploads failing.

 It gave us a bunch of these in the backen logs.

 {{{
 [Wed Apr 25 12:21:56 2012] [warn] [client x.x.x.x] (70014)End of file
 found: mod_fcgid: can't get data from http client, referer:
 http://www.example.com/the-url
 }}}

 In varnish we got the same error as reported above.

 {{{
 12 FetchError   c backend write error: 11
 }}}

 I think the severity of this issue should be raised.
