Hi,

I have a CentOS installation which is running fairly smoothly.

Today I ran ifconfig mainly to see what sort of usage has been coming across the ethernet interface, and to also check my link speed.

This is what I ended up seeing for the loopback device:

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:10301085132061223274 errors:0 dropped:0 overruns:0 frame:0
          TX packets:13981054163812689233 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:11783901785008000095 (0.6 EiB)  TX bytes:10333501021200548281 (0.9 EiB)

This just feels completely wrong - almost an EiB of data?

Any assistance in tracking down the source of these statistics would be greatly appreciated.
