Resolved Unable to configure a web server on the host <myserver.eu>

[kristobal1969]

Hello,
My webmail is sometimes very slooooooow. And I somtimes get an error 500. What is strange is that I have no probleme with the mail applications (outlook, thunderbird...).
And today I recieved this mail about my webmail (I replace the server nam by myserver.eu):

Unable to generate the web server configuration file on the host <myserver.eu> because of the following errors:

Template_Exception: nginx: [emerg] unexpected end of file, expecting ";" or "}" in /var/www/vhosts/system/myserver.eu/conf/vhost_nginx.conf:3
nginx: configuration file /etc/nginx/nginx.conf test failed

file: /opt/psa/admin/plib/Template/Writer/Webserver/Abstract.php
line: 75
code: 0

Can anybody help me understand ?

Please resolve the errors in web server configuration templates and generate the file again.

First of all check line 3 in file /var/www/vhosts/system/myserver.eu/conf/vhost_nginx.conf
Looks like this config file is misconfigured. Or remove all lines in GUI "Additional nginx directives".

Hello and thanks for your message.
There is nothing in the file vhost_nginx.conf
I ihave nothing in "Additional nginx directives"
how can I install this :
<IfModule mod_fcgid.c>
FcgidIOTimeout 120
</IfModule>
Found here
I tried to paste that code in "Additional nginx directives" but the code is red and not kept. I did that because the webmail is sometimes very slooooow but mails recieved or sent from a client application (Mail for macox or thunderbird) are not slow neither the sites nor panel access nor ftp access.

If you have an idea to help make it work better. This slowdown is quite new and happens only somes times in the day.

Hope you can help

Try to increase value of FcgidIOTimeout in /etc/httpd/conf.d/fcgid.conf file.

Check apache2 directory instead of httpd

 

[kristobal1969]

Here is what I got in apache2:

-rw-r--r-- 1 root root  7280 Sep 11 06:26 apache2.conf
drwxr-xr-x 2 root root  4096 May 15 06:25 conf-available

I can not find the folder you were talking about. In plesk.conf.d that seems near conf.d nothing interesting either. Here is the content:

drwxr-xr-x 2 root root     4096 Mar 17  2017 forwarding

Can you help again ;-) ?

I ran the locate command

oot@graphicom:/etc/apache2# locate fcgid.conf
/etc/apache2/mods-available/fcgid.conf
/etc/apache2/mods-enabled/fcgid.conf
/home/kris/dev/fd/3/dev/fd/3/dev/fd/3/dev/fd/3/etc/apache2/mods-available/fcgid.conf
/home/kris/dev/fd/3/dev/fd/3/dev/fd/3/dev/fd/3/etc/apache2/mods-enabled/fcgid.conf
/home/kris/dev/fd/3/dev/fd/3/dev/fd/3/etc/apache2/mods-available/fcgid.conf
/home/kris/dev/fd/3/dev/fd/3/dev/fd/3/etc/apache2/mods-enabled/fcgid.conf
/home/kris/dev/fd/3/dev/fd/3/etc/apache2/mods-available/fcgid.conf
/home/kris/dev/fd/3/dev/fd/3/etc/apache2/mods-enabled/fcgid.conf
/home/kris/dev/fd/3/etc/apache2/mods-available/fcgid.conf

/home/kris/etc/apache2/mods-available/fcgid.conf
/home/kris/etc/apache2/mods-enabled/fcgid.conf

Which one should I modify ?
/etc/apache2/mods-available/fcgid.conf
or
/etc/apache2/mods-enabled/fcgid.conf

Solved
In fact the problem was that I had too many connexions from users (my customers) using the webmail or at least postfix.
I hire a guy that found that I should modify /etc/courier-imap/imapd

He changed MAXDAEMONS to more that it was.

MAXDAEMONS=128

I hope that this can help anybody. Since that no more problems with error 500 or slow login in the webmail or anything slow using the webmail.
