Looks very much like the old wrapping-counter problem. If you use a 16-bit counter for a fast link, then at about 130Mb/s or so the counter gets so big that MRTG thinks it has wrapped around, hence you get this effect (I may be a bit wrong with the numbers but thats it in a nutshell). The solution is to use the SNMPv2 and 64bit high-speed counters for this interface, then everything works. Seen the same problem here, switched to use 64bit, all now OK.
