Hey @all,

whenever i send an POST-request varnish comes up with a 503 server-error.
this bug(?) is already discussed on the web, but i can´t  see how to solve this issue!
may be it belongs to the POST-size of the request?

Varnishlog tells that i am sending a

  31 TxRequest    - POST
  31 TxHeader     - Content-Type: application/x-www-form-urlencoded

but i am getting

    9 FetchError   c backend write error: 11
   31 BackendClose - [backend name]
    9 VCL_call     c error
    9 VCL_return   c deliver
    9 Length       c 488
    9 VCL_call     c deliver
    9 VCL_return   c deliver
    9 TxProtocol   c HTTP/1.1
    9 TxStatus     c 503

need help to fix it!
