Hello
 I am currently running Tor v0.2.2.6-alpha (git-1ee580407ccb9130) and this
is the error I receive running it.

Dec  5 11:50:15 XXX Tor[1300]: TLS error: unexpected close while
renegotiating (SSL_ST_OK)
Dec  5 11:50:18 XXX Tor[1300]: Tor has successfully opened a circuit. Looks
like client functionality is working.
Dec  5 11:50:18 XXX Tor[1300]: Bootstrapped 100%: Done.
Dec  5 11:50:18 XXX Tor[1300]: Now checking whether ORPort X.X.X.X:9001 and
DirPort X.X.X.X:9030 are reachable... (this may take up to 20 minutes --
look for log messages indicating success)
Dec  5 11:50:18 XXX Tor[1300]: TLS error: unexpected close while
renegotiating (SSL_ST_OK)
it than goes on to repeat the message once a minute in the log.
sockstat does show several connections yet I wonder if they are actually
able to relay through?
