TrueNAS Mini XL+ (8-bay) — appears to be discontinued
Running TrueNAS SCALE
Dual 10GbE NICs, plus IPMI
First NIC: Static IP via DHCP
Second NIC: Bridged for two VMs
Previously running 10–12 Docker containers without issue
The Problem
After upgrading to 24.10.2.1 earlier this month, I lost access to the WebUI and both VMs stopped responding. Luckily, I still had IPMI access. I reset the config and got back in, but anytime I tried to restore a previous config, the network interfaces would fail.
Eventually, I figured out that if I:
Restored the config
Stopped and removed all Docker containers
Ran docker system prune -a
…the network interfaces would start working again.
However, I’ve now discovered that running more than 4 Docker containers at once causes the system to freeze. It doesn’t matter which containers — anything beyond 4 triggers the issue.
Tried Upgrading to 25.04 — Got Worse
Hoping the issue was fixed, I upgraded to 25.04 this past Friday. Unfortunately:
Network interfaces no longer respond, even with all Docker containers stopped
Had to rebuild the entire config from scratch again
Still limited to only 4 containers — any more causes the same freeze
Even with the WebUI working again, I often have to manually reboot the VMs to get them responsive. Also, system graphs don’t show any spikes or odd behavior during these freezes. Most activity is during the night (maintenance windows), but still nothing heavy enough to explain this.
Looking for Ideas
Has anyone else run into issues like this after the recent updates?
Any suggestions for diagnostic steps or logs to check that might point me in the right direction?
