Request for one particular image ends in 502 bad gateway and proxy error
I have the Ruby on Rails-based application Redmine (based on the BitNami redmine package) running on a Windows virtual server. It runs Apache, Mongrel, Ruby, and rails.
When, in a HTML page I am building a template for, I request a static image resource named /templates/mytemplate/images/bkg.jpg - around 15 kilobytes big - I get a 502 Bad gateway error about two out of three requests. x
(source: pekkagaiser.com)
Apache's error log then contains
on Apr 12 22:50:33 2010] [error] (620018)APR does not understand this error code:
proxy: pass request body failed to 127.0.0.1:3001 (127.0.0.1)
[Mon Apr 12 22:50:33 2010] [error] proxy: pass request body failed to 127.0.0.1:3001
(127.0.0.1) from 78.34.240.113 ()
It's only for that one resource. Other, much larger images and CSS style sheets get loaded every time without problems.
Oddly, this will happen only if the image is used as a background image in a CSS style sheet. Repeated direct access tol the image in the browser works fine, even with the cache turned off. Could this be a referer problem? But I can't see how.
I know very little about Ruby nor Rails. Can anybody tell me what this could be and where I should look?
Update: On second thought, this might belong on serverfault. Migrate away if you think the same.
I reinstalled Rails and that sorted it out.
