The php service is down several times a day.
When the service goes down I have to start the service manually and it works immediately. Then minutes, hours can pass and it falls again.
Can you help me find my problem?
I have version 1.6.9 of Hestia Panel and it has happened to me with php8.1-fpm and php7.4-fpm which I use.
Its not hestia which is in charge, hestia just combines different, already existing services - if php fpm doesnt log the crash, we cant change anything - because its php fpm, so you would need to reach out to php.net.
Usualy memory limit should not directly kill a service, it should start to use the swap (and getting slow).
Have a look at the logs again, maybe syslog contains some informations.
