[support] tunnel deleted

[Etienne Roudeix]

Hello all,
I'm Shahriar's colleague,
everything's now going good. tunnels are created and no problems happened when running ordinary.
But when i try to transfer datas from cn to lfn, using FTP, one of the tunnel is deleted.
I attached the logs of HA if any of you can help me, i would appreciate
Many thanks
Etienne
