Getting an error on a plesk server witht he site running fastcgi and the upload times out or you get an error:

mod_fcgid: HTTP request length 16779013 (so far) exceeds MaxRequestLen (16777216), referer:

Source: http://kb.parallels.com/en/114842

Cause

The FcgidMaxRequestLen directive was changed from 1GB to 128KB in the mod_fcgid package, causing the limit to be triggered in many cases (source).

Resolution

The issue has been fixed since version 10.4.4, patch version = “43.”
It is fixed by setting MaxRequestLen to 15MB.
Consider upgrading your Parallels Plesk Panel installation.

Workaround

1. Change the value of MaxRequestLen in domainVirtualHost.php template.

Important: Do not change the default template. To introduce your changes to the configuration, copy the  /usr/local/psa/admin/conf/templates/default/domain/domainVirtualHost.php file to the /usr/local/psa/admin/conf/templates/custom/domain directory and then modify the copied file. See KB #115277 for more information.

2. Reconfigure domains:

/usr/local/psa/admin/bin/httpdmng --reconfigure-all
