> certain network driver in the operating system and the bug manifested only with some specific network traffic pattern. Found a similar issue in a switch stack relating to multicast stream delivery. Knowing about this class of bug and having isolated it down to the switch, as the only possible device in the path, being responsible, I filed a ticket with the appropriate team to get the stack rebooted. They were understandably skeptical of my supposed prescience and so I had to spend a considerably larger amount of time writing test cases and running deep packet captures in order to prove that a single bit, in the port field, was getting flipped under circumstances that were repeatable but not entirely explainable without even more work. Finally, they relented and agreed that, just turning it off, then on again, was indeed the best initial solution. Fortunately with all the test harnesses in place we were able to prove that it cleared the issue on that set of ports.
