dear ipv6 users :) i somehow have to manually restart aiccu and reset the 2001::/3 tunnel on my router box (which uses the tunnel and provides the subnet via radvd for clients) after a 24h disconnect which changes my remote ip. after that my log gets blown with: Jun 15 19:01:36 [aiccu] [AYIYA-beat] : Error (-1) while sending 44 bytes sent to network: Invalid argument (22)_ Jun 15 19:01:36 [aiccu] [AYIYA-tundev->tun] : Error (-1) while sending 142 bytes to network: Invalid argument (22)_ any hints before going any deeper into this?
