How to fix FastCGI timeout issues in Plesk?

Question

PHP support is currently set to: run as Fast CGI.

I keep getting these errors in my server log:

mod_fcgid: read data timeout in 45 seconds

Premature end of script headers: index.php

Should be quick fix I think, but I cant find the file to edit. Is this something I can change from Plesk.

Anyone know how to increase the timeout?

Answer 1

My solution to this was to change the PHP settings in the plesk control pannel as per the screenshot.PHP Settings

Answer 2

A solution provided in the forum of Plesk by Parallels staff

Edit the file:

/etc/httpd/conf.d/fcgid.conf

Specifically, change

FcgidIOTimeout 45

to

FcgidIOTimeout 3600

3600 seconds = 1 hour. Should be long enough for most but adjust upwards if required. I saw one example quoting 7200 seconds in there.

Finally, restart Apache to make the new setting active.

apachectl graceful

Hope it helps

In Plesk 12.x and similar go to Web Server Settings and set the following directives:

Additional directives for HTTP & HTTPS

FcgidBusyTimeout 300
FcgidIOTimeout 250

Above lines will change the timeout for scripts that are quiet too long and take too long to execute.

Additional nginx directives

proxy_read_timeout 300;

Above lines will change the proxy timeout.

If the problem persist, increase the values.

In the new version of Plesk the fcgid.conf file has moved to:

/etc/apache2/mods-available/fcgid.conf

I had some issues importing an xml file into wordpress. It kept on giving a 500 Internal Error. The error log showed:

[Wed Jul 26 13:18:00.219226 2017] [fcgid:warn] [pid 4751] [client 145.97.205.8:60155] mod_fcgid: read data timeout in 45 seconds

[Wed Jul 26 13:18:00.219505 2017] [fcgid:warn] [pid 4751] (110)Connection timed out: [client 145.97.205.8:60155] mod_fcgid: ap_pass_brigade failed in handle_request_ipc function

After following some advice - as the PHP.INI settings made no difference - i changed some settings as advised:

Original:

FcgidIOTimeout 45

To:

FcgidIOTimeout 3600

Also added:

<IfModule mod_fcgid.c>
FcgidMaxRequestsPerProcess 500
<IfModule !mod_fastcgi.c>

Worked like a charm. Thank you for your help.
