I have two unraid servers, both have Intel quad NICs with lan and guest interfaces ("inner", and one also has an iot interface "outer".  After originally running one on a 5900X (which ran great after some initial periodic hanging until I moved a few remaining items off br0), both now run on Intel 10/11th gen systems.  Anyway, those worked pretty well, also, but after migrating many of the containers from the inner server to the outer one, the outer one has started becoming non-responsive periodically.

 

I finally changed the Docker network type from ipvlan to macvlan yesterday because I hoped it would help with stability, though prior to the migration they had  both worked really well on ipvlan and I think that option offers better security - so I'm hoping to revert back at some point.  The only thought I had is that I still have a unifi-controller container that is running on a br0 sub interface and maybe the system doesn't like that any more, but it had worked fine that way on the very similar inner server.

 

When it hangs, basically the gui becomes non-responsive first.  Usually most/all the containers continue to work, at least for a while, but some recent network weirdness suggests to me that maybe things like swag stop fully passing traffic.  Sometimes I can console in, but even trying to intitiate a reboot there doesn't seem to work.  I have to do a rapid init shutdown or it never actually reboots.

Anyway, hoping someone can help me figure out the cause.  Thanks in advance for any help.

Check filesystem on cache, there ae multiple call traces but not clear to me on what's causing them, one thing you can try is to boot the server in safe mode with all docker/VMs disabled, let it run as a basic NAS for a few days, if it still crashes it's likely a hardware problem, if it doesn't start turning on the other services one by one.

Okay.  I checked the filesystem so I'll look at safe mode testing.
