I have been doing so for many years with out issue. Recently, I have been running into an issue where it maxes out my cpu on any version newer than 8.4p1-1. The solution is to downgrade to 8.4p1-1. My server machine is a dell t330 running windows 10. I am not a business despite using business grade hardware.I have tried both 20h2 and 21h1 but no luck. There are no users signed in when the issues occur and occurs within minutes of booting up. The only change from the default config is I have it running on a nonstandard port. Any advice is welcome as I really would like to upgrade to a newer version. Thanks
