Bug #160
closedThresholds don't seem to be honored for icmp traffic.

Description
When processing the attached pcap suricata generates 57789 events where snort only generates 2 one for each src of the traffic 192.168.1.44 and 192.168.1.48 contained in the pcap . It appears as if this happens because suricata does not honor thresholds for icmp traffic.

Just as an update it looks like we were missing detection to this sig previous to the following commit. So thresholding for ICMP may have been broken for some time.
