I have noticed this error in my upload log :
[Fri Apr 20 14:35:24 2012][12613] [Fri Apr 20 10:35:24 2012] upload.cgi: could not find ParserDetails.ini in Modules/XML/SAX
[Fri Apr 20 14:18:57 2012][14290] [Fri Apr 20 10:18:57 2012] upload.cgi: "my" variable $req masks earlier declaration in same scope at Plugins/uploading.pm $
I have did some modifications to my server configuration
but the load average is still high ..
