Hello,

one of my middle relays got auto limited by the ISP because of "outgooing UDP flooding ".

The VPS is pure debian8, fail2ban, pub key and nothing else installed - so I highly doubt the give reason for the traffic limitation. Also I cant find anything in the log files.

Anybody having experience with such an issue? What to check for please?

Happened once to me, in my case the culprit was a buggy DHCPv6 client (i.e. unrelated to Tor). Does your VPS utilize IPv6 with DHCPv6 and which client do you use, if so?
