Bug Description

Ubuntu mantic running on a digital ocean instance (1 vcpu, 512Mb ram, 10GB disk) with kernel 6.5.0-21-generic

When auto-refresh is triggered (usually by night) it leads to huge disk writes and GPU usage very likely due to memory usage.

Journal is attached, it doesn't provide much a part OOM killer that seems to fail.
