Hi,

This bug I believe has been reported a couple times before, one google search returns this: http://feedback.arma3.com/view.php?id=15134 which is a bit old (2013)

The issue is that after the mission is loaded, even if the server is idle for 24+ hours without any type of player interaction the CPU will entirely max out it's allocated corecount (via -cpucount)

This is occurring on the BI allocator with a stock Arma 3 server.

Thank you for your time.
