Google tells me that LPTS = Local Packet Transport Services. TAC are meaning packets that are destined for the router control plane, not the forwarding plane (ie. packets TO the router, not THROUGH the router). Response to these packets can depend on how busy the router is and also any CoPP that might be implemented. Has potentially to be true. If you have no CoPP on the devices and they are under minimal load (CPU wise) then this probably shouldn't be a factor.

Are you losing any traffic that is going through the device (ie. from ping tests) ?

Tony.
