I don't usually post on here but the recent 12.20 has been hitting 100% CPU usage easily. I reduced the threads from 500 to 300 to 200 and then finally 120. It's still the same. They would run fine at very low cpu usage at first and then suddenly just hit 100%. I've tried all the way down to 50 threads and still the same. I could run up to 500 threads or more prior to this. Is it just me?
