tinc 1.0.26 on Ubuntu 15.10 x64 sometimes crashes on startup

[Maximilian H.]

Hello,

on an x64 ubuntu 15.10 desktop tinc 1.0.26 sometimes crashes on startup
of the machine. eth0 (via good old cat6 cable, no wireless) is
configured to use dhcp. The crash does not happen often, I have seen it
in total maybe 2 or 3 times since installing 15.10 while it was still in
alpha ( July 2015 ) until today. The desktop is not shut down very
often, maybe once a week or every two weeks or even in longer intervals.

I then have to restart tinc
/etc/init.d/tinc restart

After that tinc will run fine for days and weeks and months without
crashing.

If I would have to guess I would bet on some race condition on startup,
maybe tinc is started before there are any configured network interfaces
at all ? Is that even possible ?

Thanks
BR
Max.
