This attribute records the number of times that the bus tap was
unable to receive a frame from the bus because it required more
than 255 blocks of shared memory. Each occurrence results in the
loss of the frame. This type of event should never occur during
normal operation of the module and indicates improper
configuration of the card or the occurrence of a hardware or
software fault.
The attribute's value wraps around to zero when it exceeds the
maximum permitted value.
