Module 'apcu' already loaded at Unknown#0

Server

Hello, my log contains a lot of these:
{“reqId”:“3fc84600-0e0e-4add-a455-051e0cadce5b”,“level”:3,“time”:“2018-10-02T20:27:47+02:00”,“remoteAddr”:“192.168.2.1”,“user”:“raspy”,“app”:“PHP”,“method”:“PROPFIND”,“url”:"/owncloud/remote.php/dav/files/raspy/",“message”:“Module ‘apcu’ already loaded at Unknown#0”}

Is this supposed to happen?

I do not know where to find it.

Hey,

i think this could be something which is wrong in your PHP configuration where the named module is loaded twice.

Thank you tom42,

I added

[APC]
apc.enabled=1

to /etc/php/7.0/apache2/php.ini (/etc/php/7.0/cli/php.ini does not have this entry).

but only after I found these log entries. These are the only entries with ‘apc’ in it.

Do you have any suggestions as to where the module might be loaded?

Hey,

personally when having such issue it would have a look at the PHP manual to get the knowledge how PHP is loading its modules and then apply that knowledge to see where and why it is loading it twice.

It could be also possible that it is something specific to your used linux, then it could be also possible that you can find some background information when using a search engine to search for this error.

Got it: If you have a problem, don’t ask, read a book. Thank you, I’ll pass on that wisdom.

Hey,

i think the main problem is that every environment is different and this issue can have that much origins that it is hard to tell specifically what you need to do. :confused:

With the knowledge in mind that the main topic of this forum is user support for ownCloud and not PHP i’m not sure if there are that much people able to tell you exactly what to do. :confused:

But as PHP is widely used searching a little bit around brings various topics like:
