Issue plesk-php71-fpm service freezes constantly

[King555]

The plesk-php71-fpm service on my server freezes constantly on several days of a week (usually Mondays to Wednesdays, but mainly on Tuesdays). It does not crash, it just does not respond and so my complete site does not respond. The only solution is to manually restart the service via console (or via Plesk web interface).

Why doesn't Watchdog restart the service? The monitoring is enabled, of course.

And how can I find out the reason for it?

Start by looking at the log file /var/log/plesk-php71-fpm/error.log and search for any log entries at the time of the occurrence. Then search the Plesk Support page at Plesk Help Center for relevant articles that match your problem. And/or post your log here.
Also check your syslog entries for any indications about what happened at the time of problem.
