After upgrading to Plesk 18.0.30 in Ubuntu 16.04.7 LTS apache gracefully restart seems not working well.
In this morning apache has stopped 3 times, 502 bad gateway errors. I run: service apache restart and works again but about 30 minutes after apache goes down.
In apache logs at the time it's stop:
[mpm_prefork:notice] [pid 11915] AH00171: Graceful restart requested, doing restart
[Wed Sep 16 14:00:33.871226 2020] [:alert] [pid 11923] (4)Interrupted...
