Ok so the upgrade to 6.9.0-rc1 has been mostly smooth, however I'm seeing 2 cores stuck on 100%
Noticed there are some call traces in logs, which never appeared in 6.8.3
100% usage happens in safe mode also, so not related to plugins.
The actual cores in use are rotating.
I have rolled back and forward to ensure that it was a clean upgrade, tried uninstalling plugins etc with no change.
Usage is irrespective of VM and Docker services running or not, so is something related to core OS.
Fresh diagnostics attached
