Software: PacketWise 8.x (possibly others)
Packeteer creates bandwidth management solutions such as the PacketShaper which "is the ultimate scalable platform for optimized WAN application performance?the only all-in-one solution for extending monitoring, shaping, acceleration and compression as well as centralized reporting and management across the distributed enterprise."

Both of these examples require either "look" or "touch" access to the device.
The watchdog timer will trigger a unit reset/reboot, which takes around 30 seconds. If there is no bypass mechanism in place (e.g. fiber bypass switch), service will be interrupted.
Packeteer has not responded to the initial reports.
