Hello,

I run a Tor client on a FreeBSD 14.2 server with a somewhat unreliable ue0 network interface using if_urndis tethering. It looks like a little while after Android dropped the connection and the ue0 interface was destroyed, this bug was triggered in the Tor node:

Jun  9 19:07:30 HP-DL361 Tor[44453]: circuit_detach_stream: Bug: Edge connection not in circuit's list. (on Tor 0.4.8.16 )
Jun  9 19:07:30 HP-DL361 Tor[44453]: tor_bug_occurred_: Bug: src/core/or/circuituse.c:1439: circuit_detach_stream: This line should not have been reached. (Future instances of this warning will be silenced.) (on Tor 0.4.8.16 )

This is my system configuration:

~ » uname -a && freebsd-version
FreeBSD HP-DL361 14.2-RELEASE-p1 FreeBSD 14.2-RELEASE-p1 GENERIC amd64
14.2-RELEASE-p3

I've attached some relevant log output for the node startup config and what was going on with the network interface. Let me know if any more info is needed.

Thanks
