That's what I concluded after finding the ticket, but helpful to a new exit relay operator to have this confirmed.

We know about it for quite some time and investigating. It is safe to ignore it for the moment. No sense to open a ticket about it on trac as it's already there.

It occurs on Exit relays. The faster the Exit, the more often you get it. Here is one of mine:

~$ cat /var/log/tor/tor.log | grep rendezvous | wc -l 386

only in the last ~27 hours.

For the time being we don't think it's a security risk nor something that can crash relays. But at least we are 100% sure that we are not talking about just one or two misconfigured client implementations out there that sends duplicate ESTABLISH_RENDEZVOUS cells on the same circuit.
