[Swan] tunnel error after 24h

[valentin vlasov]

Hello.
I have some tunnel made it with different partners. Only one of them give me this strange behaviour.Tunnel it's between my Libreswan 3.15 (netkey) on 2.6.32-696.16.1.el6.x86_64 (centSO 6.9) and a Cisco ASA 5520.Configuration:
config setup
        protostack=netkey
        logfile=/var/log/pluto.log
        interfaces="ipsec0=eth0 ipsec1=eth1 ipsec2=eth1:0"
        dumpdir=/var/run/pluto/
        virtual_private=%v4:10.0.0.0/8,%v4:192.168.0.0/16,%v4:172.16.0.0/12,%v4:25.0.0.0/8,%v4:100.64.0.0/10,%v6:fd00::/8,%v6:fe80::/10,%v4:!10.x.y.z/24,%v4:!10.x.s.d/24

        leftsubnet=10.x.y.z/24
        auto=start


I attach the last pluto.log from the moment of renegotiation, but only for the first conn 'di1' [same log are for other conn defined, but are too many infos...].
With this configuration, the connection 'di1' [and others] was up for 48h but in the past all goes wrong after 24h. In this case i must make service ipsec restart and all are good.
Can you give me some advice about what happend?
If you need more information please tell me.
Thanks a lot !
