PHP memory exhausted

[tess15sep]

Dear all,
I encountered the following problem. I am running multiple flowcharts at night and encounter the following error in the logs every morning:

"PHP Fatal error: Allowed memory size of 268435456 bytes exhausted..."

I have already increased the PHP memory limit to 512M at "usr/local/etc/php/conf.d/espocrm.ini". When I run 'php -r "echo ini_get('memory_limit').PHP_EOL;"' this indeed shows me 512M. Finally, when I look under adminstration -> system requirements I also see memory limit is 512M.

However, converting the number of 268435456 bytes mentioned in the error message to MB I get 256MB (Espo default I believe). Maybe I misunderstood something but can someone clarify this for me? Now I am not sure whether increasing the PHP memory limit actually worked.

The current EspoCRM version I am working in is 7.4.3.

Thanks in advance!

Can you restart apache?

also make sure the value is changed for other configurations as well, such as cli.
