Premature end of script headers

Timeout received during file upload/downloads using Plesk 11

During extended uploads or download you are getting an Internal Server Error, the error_log looks like this:

[Mon Mar 04 08:12:58 2013] [error] [client] Premature end of script headers: index.php, referer:

If you are running PHP as FastCGI you may want to look at the parameters in this file:

# vi /etc/httpd/conf.d/fcgid.conf

FcgidIdleTimeout 30
FcgidProcessLifeTime 30
FcgidMaxProcesses 20
FcgidMaxProcessesPerClass 8
FcgidMinProcessesPerClass 0
FcgidConnectTimeout 30
# FcgidIOTimeout 45
FcgidIOTimeout 240

Usually a tweak of the FcgidIOTimeout resolved the problem.

Don’t forget to restart Apache afterwards.
