Difficult to know how to respond to this. You're the first person to
report anything of this nature, so unless you can find a way to
reproduce it, there's not an obvious way forward.

Best would be a procedure to trigger the problem. Failing that, if it
happens frequently enough to be practical, I can suggest some ways of
getting some state out of the system. First line of attack would be run
strace on the running process, to see what syscalls it's making. That
would tell us if it's getting DHCPv6 packets, and if it's answering them.


Cheers,

Simon.
