Varnish 503 Service unavailable error

| After increasing the connect_timeout and first_byte_timeout values the
| erros have reduced. I also tried to get transaction for 503 error and
| following is part of the transaction for the same
| 
|   230 VCL_call     c recv lookup
|   230 VCL_call     c hash hash
|   230 VCL_call     c miss fetch
|   230 VCL_call     c error deliver

It fails to get the result from the backend.  Upgrade to 2.0.5 and look
at the FetchError tag which will hopefully explain a bit more what goes
wrong.
