Resetting ifconfig counters

[agzathot]

Hello guys i have a strange issue with my eth0 from time to time the ifconfig counters got very large numbers:

example:
eth0 Link encap:Ethernet HWaddr xxexxxx
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:263281495183500 errors:1579715814780738 dropped:526571580301590 overruns:263285790150795 frame:1316428950753975
TX packets:263285790150795 errors:1053143160603180 dropped:0 overruns:263285790150795 carrier:526571580301590
collisions:1316428950753975 txqueuelen:1000
RX bytes:263285790150795 (263.2 TB) TX bytes:263285790150795 (263.2 TB)
Interrupt:42

and when this happens i lost network connection, the only way so far i have found is to reset linux, i have try "sudo ifconfig eth0 down / up" but gto same issue, is there a way to flush the ifconfig counters ?

what can be causing the eth0 got to RX & TX 263.2 TB when is not even connected ?

any clue what to check ?
