Has anyone else noticed this? I am not sure if it’s concerning, but it’s a little untidy, at least…? $ ssh 192.168.0.240 Welcome to NVIDIA DGX Spark Version 7.2.3 (GNU/Linux 6.11.0-1016-nvidia aarch64) System information as of Tue Nov 4 07:43:55 PM EST 2025 System load: 0.9 Usage…

I’m a bit concerned about what’s running in the background. I only had Mozilla, AI Workbench Open, VS Coder just installed and it’s been at 70 to 75GB RAM consumption doing nothing, which to me, is concerning. [image]

Hi simon.thornington If you run ip -f inet6 a do you see all of those addresses on enP7s7?

Yes they are there. I had to reboot the spark to change power strips so a lot of them are gone now, but this is what I have: [image]

Sync doing clean reconnects doesn’t seem to trigger it, it might be when the laptop is taken to work and back and the Sync toolbar thing has the big red Disconnected box, aka an unclean exit or something?

I’ll look into this. Could you send an nvidia-bug-report by following these directions? [image] *** If you have a problem PLEASE read this first *** Announcements If you have a problem, and would like assistance, please follow these steps: Please always incl…

The interface has multiple IPv6 addresses likely because your LAN advertises three /64 prefixes. For each prefix, the OS creates a stable address and a temporary privacy address (used for outbound connections and rotated over time). This results in two global addresses per prefix. This is normal IPv…

Is it normal that it grows over time? I’ve seen it have 20+ ipv6 addresses if I’ve been been working on the thing for a while.

@simon.thornington how many IPv6 networks are you connecting to? Also, your interface has long address lease times, i.e: inet6 2600:4041:5c00:7800:2a33:2ff3:d3bb:b4a5/64 scope global dynamic mngtmpaddr noprefixroute valid_lft 86352sec preferred_lft 86352sec 86352sec that’s close to 24 hours!

There is only one network that I am aware of, this is at my home network. My other devices on the same network do not exhibit this, e.g. my MacBook.
