I’ve got multiple fresh installs on a Debian 12 LXC containers on Proxmox VE. I noted abnormally high CPU utilization that I’ve tied back to the UCP module. (I mid migration process for a bunch of v15 PBXes).
Before even logging into the web interface the first time the 2 CPU cores assigned to the PBX are idling around 50% utilization, as opposed to >5% without the UCP installed.
What I am seeing is a loop of these messages for a non existent user repeatedly in the logs:
