Juju models hanging? v2.9.33 with LXD@5.4

Anyone experienced the command juju models hanging forever? I can list controllers… do other things… even switch models if I can recall the names… but it seems juju models never completes nor errors out…?

machine is Kubuntu 22.04

$ juju --version
2.9.33-ubuntu-amd64
$ lxd --version
5.4

EDIT: Update, after a while I finally see an error message… though not sure how to proceed other than file a bug report

juju models
dial tcp 10.170.27.175:17070: i/o timeout
ERROR dial tcp 10.170.27.175:17070: i/o timeout

I’ve filed a bug in launchpad… and today on a different 22.04 LTS machine… I’ve got multiple LXD containers all in state DOWN … seems like somethings happened to LXD perhaps??

I can SSH into the units… reboot them but… any ideas how to get into a good state here? these charms are all unchanged from their working states way back when so… unsure what’s happened but feels like LXD has done something

I rebooted and…seems the problem went away… if it occurs again and again I’ll come back
