This is on a Sup720-3BXL by the way:

'sh mls netflow table-con detailed:'
Earl in Module 5
Detailed Netflow CAM (TCAM and ICAM) Utilization
================================================
TCAM Utilization : 100%
ICAM Utilization : 6%
Netflow TCAM count : 262024
Netflow ICAM count : 8
Netflow Creation Failures : 2085847
Netflow CAM aliases : 0

I had read about this earlier, along with 100% TCAM usage for the FIB, but that wouldn't be the case here, as we're only showing 25% of the FIB TCAM being used.

5000 lines for ACL? I don't have any experience with ACLs of that size, but it sounds like a possible problem.

If you're doing netflow export and not doing sampled netflow, I'm guessing this is where your problem is. sh mls netflow table-contention detailed
might be able to confirm or rule this out.
