The scripts for configured.d and configuring.d to add and remove IP rules (included above) are likely the culprit. @ddstreet would you like me to write that up more compactly? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to

So far so good running the latest package for 10 hours. I'll let it run another day or two but previously I would have seen the issue by now. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu.

Here's one of the new coredumps I'm getting at boot now. Note that I don't have debugging symbols installed for the PPA version of systemd. # coredumpctl gdb 714 PID: 714 (systemd-network) UID: 100 (systemd-network) GID: 102 (systemd-network) Signal: 11

I added the ppa and did a dist-upgrade then rebooted. systemd-networkd now consistently crashes once at boot (looks like a different crash though). But then everything appears to work after networkd restarts once. I will let it run and see if the invalid pointer crash happens. # journalctl -l -u

I was not able to reproduce the original issue on 237-3ubuntu10.42~202007071725~ubuntu18.04.1 after letting it run for 12+ hours. I have now installed the newer 237-3ubuntu10.42~202007081907~ubuntu18.04.1 from the same PPA. I no longer see a SEGV when the service first starts at boot, thanks! I

I've gathered several core dumps now but the stacktraces are identical. The logged reason for dumping core is "free(): invalid pointer". I wonder if there is a race condition with whatever networkd itself is doing when it reconfigures the interface (which it seems to do more aggressively for DHCP
