Problem on CIsco 7204VXR/NPE400 ==> input errors

Hi

i have a problems with one of my cisco 7204VXR/NPE400:

C7204#sh interfaces gigabitEthernet 0/0 GigabitEthernet0/0 is up, line protocol is up Hardware is i82543 (Livengood), address is 000c.cf56.6008 (bia

i have a quantity of: 133 input errors and 109 ignored

And i don't know why. on the Cisco 6500, no errors.

not a full charge of the router .....

but i see:

In "Public buffer pools" a lot of "failures".

i see to: Big buffers, 1536 bytes (total 50, permanent 50, peak 116 @ 7w0d):

total= 50 Permanent = 50 and peak at 116

i don't know what is this detail, if i understand, the system want use in peak 116 and he have only 50 ?

thanks for your help Mag
