frame-time & tick-time start to lag/drop frames after ~60 minutes #34

I've been working on building out a CasparCG system for use at convention events and things so far have been working with the exception that after about an hour the system starts to have issues with dropped/late frames, even if the system has been sitting idle and not outputting anything. Restarting the server process resolves the problem, but it will eventually start having the issue again after an hour or so. There doesn't appear to be any useful details from the logs: server_log.txt

I guess my question is, is it normal to have to periodically restart the process so often?

The system is running CasparCG server 2.2.0 on a Xenon E3-1230 based system with a Decklink Duo 2 and a GTX770 video card running under Windows 7 w/ 8gb ram.

I've seen this before on a slightly lower specced machine with 2.1 in December 2019. I didn't take the risk and got another machine to run the show and haven't investigated after as the machine is barely used anyway.

This is definitely not normal behaviour and something is significantly wrong in the system.
