I was doing some troubleshooting on the server in regards to the intermittent freezing (2-3 times a day the server could freeze for between 3 to 30 minutes), and very mysterious clean as a whistle logs. Today as I was poking around in the logs, I didn't see any errors whatsoever. I then decided to open up Task Manager and look at the Server application, and expanded it to show all of the sub items.
To my surprise I saw a green leaf next to the Gloomwood Server Java App and when I put the mouse over it, it said the UAW suspended this application for a while. So after some reading, I learned that I need to keep the Gloomwood server app up on top and not minimized to make sure it doesn't freeze. I also understand why it wasn't an issue sometimes, but was an issue other times, and that is because sometimes I left the window up, other times I left it minimized.
I am fairly confident this was the issue due to the fact when the server resumed, the icon went away. I now have taken steps to address the server intermittent freezing.
If we have any more freezes, please report them because I will take additional measures, but I know the source / reason of this freeze now.
Still working on this, seems the initial changes still showed UWP pausing the server. I set the app to High Priority, and made sure I had it up on the screen. Will keep an eye on it.
I also learned how to manually unfreeze the app in case it happens if I am near the system.
It definitely seems to be better for the past 2 days compared to prior, I am still monitoring all this. I just need to make necessary tweaks to not hit certain thresholds related to power consumption, or tagging things as ignore, but there is no way to turn it off. Going to Linux would certainly fix that, and I do eventually plan on migrating over after some extensive testing.
I will also check the power supply on the server, wonder if the power supply was stronger, if it would increase the power save / suspend thresholds too. Something to think about, but I was certain this was a server class PSU.
June 4th:
Earlier in the day, things froze up to the point I had to log out / log in - took about 3 minutes, but everything worked fine (sorry, I forgot to jot down the time when it happened, some time after 9am EST)
Now, at about 6:21 pm EST, server froze up, and I tried logging out / in again, and after 10 minutes I still cannot log back in.
FYI - not a complaint, just providing you info and times in case you can go back and see what Windows was doing at around those times, in case windows is doing funny stuff server-side...

I know we were having ISP issues today in the area, wider news AT&T having issues and some of their data lines are leased. I can login now without any issues, I see Tralen in. I noticed the server is on a KVM switch and when I am not there, I have the mouse over the application with full control, during day I use the systems and I noticed that around 11am someone said it froze for a moment and when I checked the server and put control on it, it seemed to pick up...so I think I have to leave a live keyboard/mouse connected to it for a better success rate.
Let me know if you are still having issues logging in, I am probably going to do a server reboot here soon anyway.
