SOLVED: System suddenly running at 100% CPU

Just came here to say I didn’t have this problem per se, but learned about sub streams and looking forward to implement.

Also picked up some tips from the “standard allocation” post.

Thanks to all who contribute!
 
Well my system has gone 7 days now without a fault on the CPU hitting 100%.
Im running 5.3.0.3 (07/13/2020)
When I rolled back from 5.3.7.x this version auto-offed HA in all the Cams. Fixed that. Then lowered fps on live view to 10fps. The 4 Fisheye’s were flaking out on h.265. I clicked on page defaults for those and they chose H264H. Flakiness fixed. Stable today . 10-13% cpu @ 2.6 GB Memory usage.
