Hello, I use Apache 2.2.22 on my Debian Wheezy (7 / stable) box. I run into troubles using mpm-itk and mod_fcgid (for PHP) together. As soon as I add the ITK directive "AssignUserID" to my vhost, specifying a different user than the global Apache one, mod_fcgid fails returning the following error : [Sun Jul 28 15:09:37 2013] [emerg] [client x.x.x.x] (13)Permission denied: mod_fcgid: can't lock process table in pid 1973 This bug does not seem to be related to socket permissions, as patching mod_fcgid to enlarge them does not help. Perhaps mpm-itk tries to run mod_fcgid with the global Apache user instead of the specified "AssignUserID" user... Or perhaps mod_fcgid does not take the "AssignUserID" user from mpm-itk... Steinar, the author of mpm-itk, has also been notified. http://mpm-itk.sesse.net Thank you very much for your support ! Best regards, Ben
