statgrab showing ierrors

[BiloxiGeek]

I'm seeing lots of ierrors from statgrab for both of my network ports, loopback and the IPv6 gif0 interface.

codestatgrab | grep ierrors
net.enc0.ierrors = 0
net.gif0.ierrors = 408923
net.igb0.ierrors = 10495932
net.igb1.ierrors = 1990106
net.lo0.ierrors = 31504
net.pflog0.ierrors = 6693
net.pfsync0.ierrors = 0
net.wan_stf.ierrors = 106953

Everything seems to be running just fine but this is showing up in my check_mk services as critical services. I'm curious if this is normal or something needs a bit of tweaking somewhere.

I just set up this system on a Jetway JBC323U591W, dual Intel i211-AT ports.
