how to raise PHP memory_limit

[OXYD]

Hi,

I encountered a PHP error during a trace log export through the OPNsense web interface.

Code: [Select]

OPNsense 21.1-amd64
FreeBSD 12.1-RELEASE-p12-HBSD
OpenSSL 1.1.1i 8 Dec 2020

Code: [Select]

Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 363944728 bytes) in /usr/local/opensense/mvc/app/library/OPNsense/Core/Backend.php on line 138
I think the log size is over 200MB.

My first guess is to increase the PHP variable "memory_limit".
But I don't know where to do it to be persistent.

I only found this post related to PHP:.
https://forum.opnsense.org/index.php?topic=3573.msg12174#msg12174

Multiples files are mentioned.
/usr/local/lib/php.ini
/usr/local/etc/php.ini
/usr/local/etc/rc.php_ini_setup

I don't want to mess up the setup.
Any help is welcome.

Regards

Patch for upcoming 21.7 is here: https://github.com/opnsense/core/commit/6d1b3ceab

Apply and activate using:

# opnsense-patch 6d1b3ceab
# configctl webgui restart

As mentioned, the patch will be part of the 21.7 release series so whenever you update 21.1.x the patch will be removed and you need to reapply.


Cheers,

Hello,

Thanks again for your patch, however we still have a problem related to this since we are facing the same error message :

Code: [Select]

PHP Fatal error:  Allowed memory size of 1073741824 bytes exhausted (tried to allocate 20480 bytes) in /usr/local/opnsense/mvc/app/controllers/OPNsense/Diagnostics/Api/LogController.php on line 83
As you can see, it needs a few more memory we are guessing.

Thanks for your help

Cheers

You can increase the limit as you wish, but at some point you hit a RAM hard limit. It would be better to adjust whatever you are trying to do with the excessive logging.

Hi,

We tried today with this log file.

Code: [Select]

239M    /var/log/filter.log
But it seems that the more we give, the more it asks.

Code: [Select]

cat /usr/local/opnsense/service/templates/OPNsense/WebGui/php.ini | grep memory_limit
memory_limit = 1700M

Code: [Select]

Do you know what might be the problem ?

Please do not use more than 100 MB for circular log files. The log file read time increases exponentially when adding more space to it.
