UTM using 47GB RAM after running a small VM for a few days.

Describe the issue

After running a VM with Home Assistant (haos_ova-14.2.qcow2) for a few days, UTM was taking over 47GB of RAM. Only 2GB were allocated to the VM.
There is likely a memory leak. I wonder if it's related to sound support, as the VM seemed to use audio input, causing macOS to display a "microphone in use by UTM" icon in the top menu bar.

Configuration

• UTM Version: 4.6.4
• macOS Version: 15.3
• Mac Chip (Intel, M1, ...): M4 Pro 64GB

Debug log

I didn't initially have debug enabled but here is a log after 40 minutes of use :
