System freeze when installing or updating apps/VMs on TrueNAS SCALE 25.10.0

Hi everyone,

I’ve been having an issue with my TrueNAS SCALE system that has persisted since version 24.04 and still exists on 25.10.0.

System details:

  • OS Version: 25.10.0

  • Product: MC12-LE0-00

  • CPU: AMD Ryzen 7 3700X (8-Core)

  • Memory: 63 GiB (non-ECC)

  • Apps: ~15

  • VMs: 2

Problem description:
Most of the time, the system runs perfectly fine. However, whenever I try to install a new app or create a new VM, the entire TrueNAS system seems to freeze for several minutes.

During this time:

  • I can’t access any running apps or VMs (for example, Home Assistant).

  • My external uptime monitor (Uptime Kuma running on another machine) reports downtime for all my services like Pi-hole and Home Assistant.

After about 5 minutes, everything comes back online as if nothing happened.

The same thing sometimes happens when I update Home Assistant (VM) or update existing apps.

Has anyone else experienced similar behavior or found a cause for this?
Any suggestions on what to check (logs, resource usage, etc.) would be appreciated.

Thanks in advance!
