I've been noticing a bug on a Samsung Galaxy S3 & Samsung Galaxy Note 2 (and
possibly other devices too) when the bearer switches from wifi to 3G where I
can no longer connect to a host.
If I undefine USE_ARES (build without c-ares) then this issue is gone, but I
would like to keep c-ares for performance.
This is probably the boring but known old story about c-ares not noticing when
your /etc/resolv.conf gets updated with a new server so it will remain trying
to use the old one...
In the c-ares project (and probably also here) we've discussed and debated
different ways that c-ares could re-init itself when that happens so that it
would load the new server set, but nobody has yet taken it all the way
through.
See for example the ares_reinit thread from 2011:
