yes it is the entire file
I also had this issue with SNMP of a querying another system
so it's not that

which was a 100mbps link to a switch and it looked like
IF-MIB::ifInOctets.1 = Counter32: 16378112
IF-MIB::ifInOctets.2 = Counter32: 16270013
IF-MIB::ifInOctets.3 = Counter32: 0
IF-MIB::ifInOctets.4 = Counter32: 993158
IF-MIB::ifOutOctets.1 = Counter32: 2152473
IF-MIB::ifOutOctets.2 = Counter32: 10148053
IF-MIB::ifOutOctets.3 = Counter32: 0
IF-MIB::ifOutOctets.4 = Counter32: 996604

and I still gort this out of range data

I woner is there any kind of system based issue that could cause this?? or 
am I on the wrong track

as requested top lines of MRTG Log file is
058571227 13455 10775
1058571227 0 0 0 0
1058570944 4294967296 -4629708749173424128 2885555223558881280 0
