Incus Resources API Shows Static Load/Memory Data Despite System Changes

I have read a little about how the cache of resources is working

it seems it caches only for 10 seconds, but for me it seems to cache forever. I ran this stress test on a Rocky machine for more than 10 seconds:

stress --cpu 4 --vm 2 --vm-bytes 1G --timeout 60s
stress: info: [2665] dispatching hogs: 4 cpu, 0 io, 2 vm, 0 hdd
stress: info: [2665] successful run completed in 60s

But the Incus API resources load data is always the same. In the code it seems to call /proc/loadavg, which is correct when I run the load test, but the Incus API data is always the same. There is something wrong somewhere, and this is the data I collected on the Incus server:

[root@localhost ~]# cat /proc/loadavg
