How to understand from which php processes the server hangs on Debian?

Question

PHP

There is a server on Debian.
It runs a php crm system.
Various php scripts are launched by cron, etc.
Periodically, the server hangs completely, so you can't even log in via ssh.
Through atop -r it was revealed that this is due to the large number of php processes at that moment.
Tell me how (what kind of logger or something else?) Can I identify which scripts are currently running?
