I recently ran EasyApache to compile apache with mod_deflate. After this everything was fine except for scripts that also contain some ajax with forms. Nginx is setup as a proxy to apache to handle static file requests. I'm getting this error when accessing a file upload form: "[error] 24263#0: *485033126 upstream prematurely closed connection while reading response header from upstream," I've since re-compiled apached without mod_deflate. This did not work. Nothing else has changed in the configuration. The only thing I could think of is that something else updated to the latest version and there is a bug in the code somewhere. Any ideas?
I was running php 5.2.9 and updated to 5.2.17 - something in there fixed the problem. (I have other reasons for not updating to 5.3.x)
