Mongrel users - Jan 2008 - Mongrel stops to loading the page in browser

Hi all,

I have a problem with mongrel-1.1.2 running with Apache Apache/2.0.61
and MySQL 5.0.45 on FreeBSD 6.1.

I''m developing my application with InstantRails that uses Mongrel and
everything is working great. I have about 30 shops in a table. I also
store the logo images (png files) in the table for each shop. Under
Windows/InstantRails everything is working correct.

When i however copy the application to the Unix Box, start Mongrel and
load the page i get an error in the mongrel.log file with following
text:


** Changing group to "www".
** Changing user to "www".
** Installing debugging prefixed filters. Look in log/mongrel_debug for
the files.
** Starting Rails with development environment...
** Rails loaded.
** Loading any Rails specific GemPlugins
** Signals ready.  TERM => stop.  USR2 => restart.  INT => stop (no
restart).
** Rails signals registered.  HUP => reload (without restart).  It might
not work well.
** Mongrel 1.1.2 available at 0.0.0.0:3000
** Writing PID file to tmp/pids/mongrel.pid

This error message tells me that there is an error in the
http_response.rb file happening at the method send_data. But i could not
determine what the problem is exactly. As everything is working with
InstantRails i really don''t know where to start searching the problem
as
the code in my eyes should be working.

When i remove the "image_tag" line from the rhtml file so that the
images are not loading, then the browser is loading everything. If the
"image_tag" line is present, then the browser will stop after 2 thirds
of displaying the html.

So it seems an image can not be loaded or displayed.

<% @topshops.each do |shop| %>
          <table width="100%"  border="0"
cellspacing="0"

            <tr>
              <td class="shops"><table width="100%"

          </table>
          <br>
<% end %>


show_picture_of_partner:
def show_picture_of_partner
       partner = Partner.find(params[:id])
       send_data(partner.picture_data, :type =>
partner.picture_content_type, :filename => partner.picture_name,
:dispositon => ''inline'')
    end

Can anybody tell me what the problem could be? Or what to do better to
get around this problem?

Thanks,
Chris

Looks like the user Mongrel is running as (www) does not have permission to
