Comment(by zwol):

 I generated new logs from both client and server, at "debug" level, with
 "SafeLogging 0".  The client is 172.19.151.215 and the server (bridge) is
 128.2.142.99. It looks like the offending CREATE cell is indeed coming
 from another relay (185.21.101.40 = afo3.torproject.afo-tm.org).  I'm not
 sure why this would happen for a relay with PublishServerDescriptor 0 set,
 though.

 For the record, here is the complete server torrc:
