Hi Eriberto,
thanks for testing again. I repeated my tests and gradually upgraded
from jessie to stable-updates to stretch with libpcap0.8 and netdiscover
without visible failure (yep, including the libc6 2.19 from jessie - no
trouble).
I then upgraded to stretch (since that's the only sane way to test with
the current libc6) and expected to get a stacktrace (and then proceed to
install backports from jessie), but it *worked*. If this worked in a VM,
I'd have several snapshots at this point...
I went back to the installed OS and it worked there as well. I'm kind of
annoyed by the fact that I can't reproduce what didn't work for months
(every few weeks the need to find a host occured, no reliable interval).
Something's wrong, and I can't tell what...
How can we proceed (until I find out how to trigger that bug again in a
reproducible way)? Keep this here on "unreproducible"?
Thanks for the efforts so far. Regarding strace: I tried that last time
(in december), but I couldn't find something useful for me. I still have
those logs (enabled -ff). I attached those (I hope that's okay). 30685
was the pid of the netdiscover process. I removed two unnecessary large
files containing nanosleeps/sendtos/polls only (pid 30690, 30691).
