"ignored", "deferred" vs "drops"

7513; IOS 11.1(5a); VIP2 fastether hw 2.4, sw 21.40, ROM Monitor version 17.0

what do we learn if packets are being ignored and/or deferred much more
than dropped?

do drops only happen from cpu memory shortfalls or can cpu processor
load also be implicated?  anything else that can generate "drops" in "sho int"?

do ignored/deferred packets implicate interface memory, interface processor,
or something else?

TIA,

There is a problem with interface buffers if you have ignored but not dropped
packets. A simmilar problem is known for AGS+ and cbus interfaces (IOS
10.X), there is no sign for comming up of this problem, anyway. Everything
seems to be o.k. (the output of show ... commands), but the interface does
not accept any incomming packet.
