Do you not have some IPv4 routes pointing to tun1 occasionally? Try to "tcpdump -i tun1". Provided your tcpdump is good one, it can be useful. If it outputs something, make "tcpdump -i tun1 -s 256 -w dumpresult", wait until the event will happen, record its timestamp from syslog and send this to me.
