Hello again evergreen,

There are many reports regarding this error see below:

1) Stuck in "Partial results are valid but processing is incomplete" #62 2) Apache 2.2: Partial results are valid but processing is incomplete, unable to stat file (X-Sendfile) 3) proxy_fcgi:error (70008)Partial results are valid but processing is incomplete. AH01075 4) Bug 55475 - mod_proxy breaks HTTP chunked transfer coding etc... etc...

Can you download the latest version of Apache (server) / Apache2::Request (client) and try again? I do not believe that the bug comes from the client side it looks it is coming from the server side. My recommendation is to update both on the latest version (theoretically the bug is fixed) and try again.

Hopefully after you should not see this problem any more.

Hope this helps, BR.
