Interesting turn of events… over the last few days I’ve updated my network drivers (via Windows update) …
Intel 82579V Gigabit card was running 12.15.22.6 - 4/04/2016 (Microsoft Driver Provider)
Updated to version 12.15.31.4 - 25-07-2016 (Intel Driver Provider)
This did not seem to help (or did not seem to as I ran into the high CPU usage again)…
However, during the issue currently with PMP Playback Error I was messing around with secure connections, optimized the database, cleaned bundles, reinstalled Plex and then ended up running the Plex installer again and running a ‘repair’… I also updated my NVIDIA drivers… So far Plex has been running for around 24 hours without the 100% CPU load issue for the first time in over a month…
I’m unfortunately not too sure what might have improved things (or combination of changes) but I’m hoping it continues to no longer cause any issues… as in the past I found I could not go any longer than say 2-3 hours without running into the high CPU load issue… fingers crossed it might be resolved!
P.S. During the issues I had run updated versions of Plex and experienced this issue across the last few updates, what I did not do before was perform a “repair” on the installation so it’s possible that might of helped as that’s something I don’t belive I tried before (although it’s been so long I can’t be 100% sure as I did try allot)… good luck to anyone else that is still having thing issue perahps try some of the items listed above and see if it might help you as well!
