This is a known bug (one of many) in the Lance ethernet chip. This
particular bug results from transmit memory underflow. Bug ID: 1029247,
1019513, 1029316.  A patch is available from Sun; it's a replacement for
the kernel module "if_le.o", for sun3x, sun4 and sun4c architectures, for
SunOS 4.0.3.

Supposedly, this bug is fairly harmless (doesn't crash the system) and
affects mainly performance.
