Hello,
wondering if it wouldn't be better to get the hostname once at startup,
rather than doing it each time a new cookie is needed.
On the other hand, note that you can set server_id for each kamailio
instance to make it uniquely identifiable, which is also important for
sruid generator (although that uses random and startup timestamp as well).
Also, sometime the local hostname overlaps, seen lots of servers using
just 'www' or 'debian'. So ensuring the uniqueness was shifted to the
sysadmins of the network nodes.
Cheers,
Daniel
