[c-nsp] sup720 ICMP redirects "once per second"

Does anyone know which knob controls the "only send 1 ICMP redirect / 
sec" on an HSRP-enabled SVI on 6500/sup720 (SXJ IOS)? Is there a "show" 
command for the defaults / current setting?

Note: I am not talking about the redirect MLS rate-limiter here; that's 
disabled. I'm seeing constant traffic flowing and would expect constant 
ICMP redirects, but that's not happening - they're coming at regular 
1-second intervals, regardless of the underlying packet arrival rate.
