Many moons ago, a software package called VMNET kept crashing the FDDI ring at the JVNC, near Princeton University. Basically, VMNET was layering IBM's NJE protocol used by Bitnet over TCP/IP - and the format of an NJE SIGNON packet to start a link up, when stuffed into the FDDI format (which on the wire was some NRZI or some such thing), resulted in a too-long run of zero bits (basically, no laser for a long time), causing the other end to lose timing sync due to clock drift.
