I think I found the problem. When I upgraded the server OS on Tuesday I had a second GUI login session open for the admin user as I needed to sudo to fix some permissions, etc (aka fast user switching). When I checked on the application early Saturday AM I realized I had left that user logged in with an idle terminal session. I also found that when I remotely logged in to to check on the 'web client' user that 4D was not running, but quickly launched (my login woke the system up). I suspect that power management features were causing the network and/or hard disks to 'sleep' at 3AM. We have not had problems since logging that user out. Therefore, even though you may think that Power Nap is configured to be off, it isn't totally.

That is assuming of course that any system level activity would be logged. The closest entry is at 3:01 and that is when my monitoring script emails me the first of many messages that there is a problem. I was mainly asking here in case those that are more in tune with current Mac goings on were aware of anything new in High Sierra that might have caused problems with 4D. I'm not familiar with the use of 4D's debug/request log. Can that be turned on easily, or do I have to recompile the structure to enable it? I'm mainly interested in what is going on at the client. I'd also guess that whatever is hanging 4D might not get logged to the server.
