As per Cisco Documentation, this warning is informing you that you are maxing the TCAM resource allocation for a specific feature. You should be able to see your utilisation/allocation per feature via:

show system internal access-list resource utilization

You may also be able to perform TCAM carving to reallocate resources if required.

  • @Blackmetal, that means you need to change the allocation of your TCAM, reducing the TCAM allocated to the things with little usage, and giving more to what is full.
