[STDERR] PHP Fatal error: Out of memory
-
Hello,
I hope this email finds you well. I am writing to report an issue I have encountered with your Super Page Cache for Cloudflare plugin on my WordPress website. Specifically, the issue occurs when the Octolooks WordPress plugin starts its crawling job while your plugin is active. When this happens, 7-8 times per day my site experiences a “PHP Fatal error: Out of memory” issue, in php logs.
Upon deactivating the Super Page Cache for Cloudflare plugin, the error stops appearing, leading me to believe that the issue is directly related to your plugin’s interaction with the Octolooks plugin. For your reference, my website is hosted on an Ubuntu Server 22.04, running LiteSpeed Web Server and PHP version 8.1.
The specific error messages I have encountered are:
2023-04-20 22:31:18.334578 [NOTICE] [28615] [172.68.62.129:31568:HTTP2-1#sportlive.gr] [STDERR] PHP Fatal error: Out of memory (allocated 190857216) (tried to allocate 20480 bytes) in /home/*******.gr/public_html/wp-includes/class-wpdb.php on line 2397

- Increased the PHP memory limit in both the
php.iniandwp-config.phpfiles. - Deactivated and reactivated both the Super Page Cache for Cloudflare and Octolooks plugins to check for conflicts.
- Optimized my WordPress installation by updating WordPress, themes, and plugins, using a caching plugin, and optimizing the database.
- I tried to change version to 4.7.2 and 4.7.3 and change Disable cache purging using queue and Purge HTML pages only options but I still see the out of memory error at least 7-8 times per day.
When i have this out of memory error in php 8.1 i cannot access the Octolooks plugin , returning an error msg. When i disable Super Page Cache for Cloudflare plugin after a while, i can access the Octolooks plugin
So after many trials and errors I tried to totally disable for a whole day the Super Page Cache for Cloudflare and see what happens. It seems like the out of memory error never returned.
Do you think that there is a incompatibility with a Third-party plugin?
Despite these efforts, the issue persists. As a result, I kindly request your assistance in identifying and resolving the underlying cause of the memory error. Any guidance, possible solutions, or workarounds would be greatly appreciated.
Thank you for your time and attention. I look forward to hearing from you soon.
Regards,
Michael

Hello again and thanks for your suggestions.
I put your options but its not working. I cannot even access the backend of WordPress. The only thing i can do to access it, is to clear the whole cache from https://www.cloudflare.com/ website or to disable the Super Page Cache for Cloudflare plugin from ftp client by renaming it.
With previous VPS and php 7.4 i didn’t had these errors only when i moved to php8.1
No the memory allocated was 4GB in php only, server has 16GB Ram. define(‘WP_MEMORY_LIMIT’, ‘4048M’);
Now i have the caching plugin disabled for 4-5 days and my php logs are clear of out of memory errors, if I enabled it again probably the errors will return.
Hi @diriras,
I honestly have no idea what to say here. Are you using fallback cache, can you try disabling it if it is enabled? Same for the preloader?I would also encourage you to download the WP Server Health Stats plugin to see the memory limit shown there. Generally you don’t need to set the memory limit at the WP config level but rather at
php.inilevel.Hello,
No I am not using anything, failcache or preloader all disabled.
The only thing I have enabled is Purge cache for related pages only – (recommended) and i still having the out of memory error.
Now that I changed to purge whole cache the error stops appearing. I enabled the preloader just to check it and still no errors! Seems like the errors only exists when caching is kept at Cloudflare servers, that its very strange because I haven’t change anything in the settings or the VPS configuration except php v8.1!
memory_limit = 512M at php.ini file
Hello again, getting back to this issue i want to point out that Ips that appearing in the PHP error logs are from cloudflare .

Is there any option to stall the caching for a bit until the crawling jobs to finish?
Also in the logs i can see the below the name “scrape”, do you think this is an issue? I tried to bypass it in the plugin via *scrape* etc but it didnt worked. The ONLY way to get back into the scrape plugin page it to clear ALL the cache!
