Hi,

I’m using newrelic to monitor several applications in my shared hosting account @webfaction. It works great and the information I get is very useful. Today I checked the log files and noticed that my php log file get this warning for very php execution:

[10-May-2014 04:58:13 UTC] PHP Warning: Module ‘newrelic’ already loaded in Unknown on line 0
[10-May-2014 04:58:16 UTC] PHP Warning: Module ‘newrelic’ already loaded in Unknown on line 0
[10-May-2014 04:58:17 UTC] PHP Warning: Module ‘newrelic’ already loaded in Unknown on line 0
[10-May-2014 04:58:18 UTC] PHP Warning: Module ‘newrelic’ already loaded in Unknown on line 0

Is it possible to configure the client to get rid of them? I tried already to change error_reporting inside the php.ini file, but this doesn’t helped.

These warnings are typically caused from having multiple:

extension="newrelic.so"

lines in your php.ini, newrelic.ini, etc. Check out the .ini files that are getting parsed (phpinfo()), and make sure there is only a single line loading the New Relic PHP agent.

Same problem

/etc/php5/apache2/conf.d/05-opcache.ini, /etc/php5/apache2/conf.d/10-pdo.ini, /etc/php5/apache2/conf.d/20-gd.ini, /etc/php5/apache2/conf.d/20-json.ini, /etc/php5/apache2/conf.d/20-mcrypt.ini, /etc/php5/apache2/conf.d/20-mysql.ini, /etc/php5/apache2/conf.d/20-mysqli.ini, /etc/php5/apache2/conf.d/20-newrelic.ini, /etc/php5/apache2/conf.d/20-pdo_mysql.ini, /etc/php5/apache2/conf.d/20-readline.ini, /etc/php5/apache2/conf.d/newrelic.ini

I would recommend checking out this thread’s post that discusses the same issue with a possible resolution. Many people were able to resolve it by removing their newrelic.ini when their conf.d directory held both a newrelic.ini and a 20-newrelic.ini.

October 10th. Can not believe this issue hasn’t been resolved. It still happening. What causing two nerelic.ini files?

#6

According to your phpinfo(), are

/etc/php5/apache2/conf.d/20-newrelic.ini, 
/etc/php5/apache2/conf.d/newrelic.ini

both getting parsed at this time? As Max has advised, you should try to remove the newrelic.ini to avoid this warning.

Hey BCollins,
Thank you for the reply. Well. I have removed that file 1 day ago and I still get the issue, maybe I need to reboot the system. I think I maybe know what causing this issue. Instructions for installing PHP application and Server tracking are pretty much the same. So, we maybe accidentally install some components twice.

Second thing… I have this info while doing apt-get update and that is why I assume this:

W: Duplicate sources.list entry http://apt.newrelic.com/debian/ newrelic/non-free amd64 Packages (/var/lib/apt/lists/apt.newrelic.com_debian_dists_newrelic_non-free_binary-amd64_Packages)

W: Duplicate sources.list entry http://apt.newrelic.com/debian/ newrelic/non-free i386 Packages (/var/lib/apt/lists/apt.newrelic.com_debian_dists_newrelic_non-free_binary-i386_Packages)

Often changes like this can necessitate restarting at least the daemon. Have you tried restarting at this point and if so, has it helped alleviate the problem?

#9

Hey Lisa, sorry for the delay. Yes, I’ve reboot the whole machine. It hasn’t helped I still get that Cron mail.

I have just now seen that I have newrelic.ini in /etc/php5/CLI/conf.d/ not only apache2 I think I have solved the problem…

But I still seeing

W: Duplicate sources.list entry http://apt.newrelic.com/debian/ newrelic/non-free amd64 Packages (/var/lib/apt/lists/apt.newrelic.com_debian_dists_newrelic_non-free_binary-amd64_Packages)

W: Duplicate sources.list entry http://apt.newrelic.com/debian/ newrelic/non-free i386 Packages (/var/lib/apt/lists/apt.newrelic.com_debian_dists_newrelic_non-free_binary-i386_Packages)

when running apt-get update and upgrade it still remains…

Here is my lib package file http://pastebin.com/hfNyEs5w

Hi @jovic_zarko

The message you are seeing indicates that you have newrelic listed twice in your sources.list to resolve this issue you should comment out one of the newrelic entries.

#11

The apt file for New Relic is in /etc/apt/sources.list.d/newrelic.list so that’s where duplicates should be removed from.

Thank you for offering help @kermit!

The duplicate .ini file problem is a problem within you installation routines. Just try the following:

Install NewRelic as described here: https://docs.newrelic.com/docs/agents/php-agent/installation/php-agent-installation-ubuntu-debian

And now it gets interesting:

  • Install newrelic-php5
  • It places a already configured file /etc/php5/mods-available/newrelic.ini with a symlink to /etc/php5/apache2/conf.d/20-newrelic.ini
  • Run sudo newrelic-install install (This is where it breaks)
  • newrelic-install does some $foo and places /etc/php5/apache2/conf.d/newrelic.ini as a file. But it does not clean up the already placed files/symlinks /etc/php5/mods-available/newrelic.ini /etc/php5/apache2/conf.d/20-newrelic.ini

After doing the describe steps you have:

  • /etc/php5/apache2/conf.d/20-newrelic.ini and /etc/php5/apache2/conf.d/newrelic.ini
  • Both contain the following line
 extension = "newrelic.so"

Here is a full log of what I did: http://pastebin.com/XQv8vfhw

Oh and if you already touching the deb package please ensure that a “apt-get purge newrelic-php5” cleans everything which it places…

Please fix this a soon as possible!
