Issue Apache hangs (mod_fcgid) with Debian 7

[waterboy]

Hi,

after doing lots of updating, apache tends to hang, with the log showing many

[warn] mod_fcgid: too much processes, please increase FCGID_MAX_APPLICATION​

System info from Plesk:

CPU Intel(R) Xeon(R) CPU E3-1271 v3 @ 3.60GHz (8 core(s))
Version Plesk Onyx v17.0.17_build1700161028.14 os_Debian 7.0
OS Debian 7.11​

This seems to directly address the issue: https://kb.plesk.com/en/130473

The path seems to be valid for Debian 8 only, though (and not sure about the arch). How can I patch my system?

Thanks you

I can only recommend creating a request to support team to do the in-depth investigation to find the reason and to fix it. Please create a ticket to support at https://cscontact.plesk.com/form/32/?Product=Plesk

Hi warerboy,

have you create a ticket to plesk support ?

We have the same issue on a customer server with the same setup

Version Plesk Onyx v17.0.17

OS Debian 7.11

Unfortunately not. As I got the license through a reseller, I need to get a support plan first.

You need to find where your files are in debian, i can only help for centos, but apache is apache, its the same.

Find fcgid.conf setup in /etc/httpd/conf.d

Adjust it to your needs, google for what others use and have to say about it. fine-tune over some period of time to see what works the best for your type of websites.

Ours is

# This is the Apache server configuration file for providing FastCGI support
# via mod_fcgid
#
# Documentation is available at http://fastcgi.coremail.cn/doc.htm

LoadModule fcgid_module modules/mod_fcgid.so

<IfModule mod_fcgid.c>

<IfModule !mod_fastcgi.c>
    AddHandler fcgid-script fcg fcgi fpl
</IfModule>

  FcgidIPCDir /var/run/mod_fcgid/sock
  FcgidProcessTableFile /var/run/mod_fcgid/fcgid_shm

##FcgidIdleTimeout default = 300
   FcgidIdleTimeout 300

##FcgidProcessLifeTime default = 3600
#  FcgidProcessLifeTime 300

##FcgidMaxProcesses default = 1000
#  FcgidMaxProcesses 32

##FcgidMaxProcessesPerClass default = 100
#  FcgidMaxProcessesPerClass 32
#  FcgidMinProcessesPerClass 0
  FcgidConnectTimeout 30
  FcgidIOTimeout 300
  FcgidInitialEnv RAILS_ENV production
  FcgidIdleScanInterval 10
  FcgidMaxRequestLen 1073741824


</IfModule>

## = the default, commented if we use the default but left in there to know it
# = what was originaly there

save and restart apache.

You might want to empty /var/run/mod_fcgid/sock/ from time to time, just to clean up.

AGAIN: these are paths on centos, on debian it might be in an other location.

hope this helps

Jan

Have you tried to edit /etc/httpd/conf.d/fcgid.conf and set FcgidMaxProcesses to a higher value? Restart web server afterwards. Details on FastCGI configuration options: https://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html

[Sorry @Linulex, this post was in the making while you were posting yours.]

 

[waterboy]

Thank you - very helpful. I've upped the limit a bit in the conf file and will see if it helps. Not much server load anyway, but only started to happen after the update; so hopefully this fixes the problem.

 

[Linulex]

Plesk sometimes overwrites fcgid.conf at an update. Simply get your old back from a backup, restart apache and your good to go (till the next update).

We have monitors in place that mail us when files are changed we don't want changed.
