Great work, Stipe! That was really quick.
What about connected smsbox'es / sqlbox'es to the bearerbox when reload happens? Bearerbox is not closing the connection port right (so it's still accepting requests from smsbox / sqlbox)? 2012/10/20 Stipe Tolj <st...@kannel.org> > Hi list, > > ok, this has been long awaited I guess: graceful restarting of Kannel > bearerbox. > > At the moment we can shutdown a specific SMSC and restart it again.
