This is not normal.

What does your per-interface config look like?

Are you sampling?

What linecards are you using?  Are they DFC4s or CFC linecards?

Just as an aside, it would be advisable not to use the collect verb for the input interface, but rather to use the match verb in order to use input ifindex as a key field.  'Collect' is for non-key fields.
