    I have “apcupsd — a daemon for controlling most APC UPSes” running on the server side. When power is lost and the server is running on the UPS the session freezes. Just a gray screen. When the power comes back up, it resumes as is nothing happened.

    So I’m suspecting there is some interaction with apcupsd or other power management process issues?

    Does the server have a monitor? If so, are you able to check it locally when the issue occurs? Is the local screen also grey?

    The logs might show some hints as to what is happening and if NoMachine is the cause, even though it seems more on the system side than in the NoMachine software. Please check the instructions in the following article, making sure you reproduce the problem before gathering the logs. Submit them to forum[at]nomachine[dot]com making sure to reference the title of your topic in the email subject. Thanks!
