Hello , I have a performance problem.  
I have Ignition installed on virtual server, which I am accessing using remote desktop control.  
Lately my whole system is freezing and not letting me do anything, but closing the remote desktop control and reopening it solves it.  
any solution to the problem?

I copy the log here:

The ClockDriftDetector messages only show brief (1-second) pauses, not a total lockup. Look for something else in the log.

(ClockDriftDetector messages that are barely over the limit suggest a server that is _slightly_ overloaded.)

I can’t find any errors in the log
