I maintain my own managed server with php7.3. Every few days my website is suddenly unavailable.
My server hoster said that the PHP processes for the domain were used up and therefore the site was not accessible.
The only recent change in php.ini is opcache.interned_strings_buffer = 64 (previously 8).
- Can this be the reason?
- How can I prevent the PHP processes from overflowing or what do I have to do to ensure that the PHP processes are automatically terminated in the event of an overload or that the server restarts in such a case?
