This happens on all of my servers (C7 and C8) at the same time everyday.  BUT the time is different everyday.

I suspect it may be deliberate and part of nightly auto-SSL renewals.

Well yeah.....that's is kinda obvious even to the blind.

But, it's the only process that is restarting apache at least once a day, everyday.

Strange that YOU didn't mention it!  >:(  ::)
In an Apache only installation, then a reload would be sufficient but I suspect that a restart is used, to cater for all (nginx included) installations.

after all sl operations apache restarts itself and sells:

   [mpm_event:notice] [pid 3838130:tid 139681793718144] AH00493: SIGUSR1 received. Do a graceful reboot

Is this solution a solution?
