Yeah, this is a bug. When working as intended, the message would read:
kernel: Limiting closed port RST response from 201 to 200 packets/sec
The first value would be higher than the 2nd value
(net.inet.icmp.icmplim). It should only alert if it is actually limiting
the response rate.
You can mute it by setting: net.inet.icmp.icmplim_output=0
