Hi. I'm running Apache/2.2.16 (Ubuntu) , libapache2-mod-fcgid 1:2.3.5-2ubuntu0.1, php5-cgi 5.3.3-1ubuntu9.6. on Ubuntu 10.10 LTS, in a Virtualmin LAMP stack. Each Virtualhost runs suexec, thus the need for mod-fcgid so that each site is running under its own user account. I have a clean install of PHPWiki , latest stable version. I'm trying to import the data from the old install of PHPWiki (3.2 MB zip), using the restore feature, every time I try the restore the process crashes with "500 Internal server error" the the following in the logs : [Wed Nov 16 10:21:14 2011] [warn] [client 192.168.69.237] mod_fcgid: read data timeout in 31 seconds, referer: http://test-phpwiki.example.com/index.php/PhpWikiAdministration [Wed Nov 16 10:21:14 2011] [warn] [client 192.168.69.237] (110)Connection timed out: mod_fcgid: ap_pass_brigade failed in handle_request function, referer: http://test-phpwiki.example.com/index.php/PhpWikiAdministration I have adjusted every setting I can find in php, mod-fcgid, and apache. I'v googled for the last day and a half with no clear answer. Configuration as follows: root@nzhmlapp04:/home/phpwiki# cat fcgi-bin/php5.fcgi #!/bin/bash PHPRC=$PWD/../etc/php5 export PHP_FCGI_MAX_REQUESTS=5000 export PHP_FCGI_CHILDREN=8 export PHPRC umask 022
