TINC Restarting every few seconds



  • I've got two networks Site A and Site B.
    Both pfsense instances are the default gateways for each site.

    I will eventually be adding more hosts to this TINC mesh VPN network (hence why I'm using TINC, and not OpenVPN or IPSEC).

    Site A config:
    WAN: siteA.fqdn.org
    LAN: 172.19.0.0/16
    Lan IP: 172.19.2.1

    Site B config:
    WAN: siteB.fqdn.org
    LAN: 172.25.0.0/24
    Lan IP: 172.25.0.1

    The gateways can ping each other, but can't ping behind each other reliably (172.19.2.1 can't ping 172.25.0.10 for example). Some hosts work intermittantly, others fail with "ping: sendto: host is down". That may be beyond the scope of this question.

    The main issue I'm having is a random restart of the "tincd" process on Site A. The default logging level is too low to get anything useful. Even killing the process and starting it manually only gets a cryptic "Got TERM signal" with no indication of the signal source.

    Could it be some buried watchdog somewhere? Both hosts are running 2.4.4-1-RELEASE and tinc-1.0.35
