Hi,
during network driver testing I sometimes do a stress test with

while true; do ifconfig vio0 inet6 autoconf; done &

After I stop these jobs, "ifconfig vio0 autoconf" does not work any more
because dhcpleased has died:

This is obviously not a severe bug, but slaacd survives the stress test.
Maybe dhcpleased could improve its error handling, too?
Is your test system newer than this commit?
No, it was not newer. I have re-installed latest snapshot from Tue Sep
3 23:49:36 MDT 2024 and dhcpleased still dies. The messages are not
always the same, though:

Even though there is no "fatal" message in the last run, dhcpleased is
still gone.
Cheers,
