Suricata

Some memleaks are observed when running against pcaps that are comprised of - kerberos/nfs/ike traffic.
Using the source suricata rules ( https://github.com/OISF/suricata/blob/master/rules/ipsec-events.rules ).
Observation - running the same routine/test against traffic that is exclusively smb/http/dns/tls/ssh/smtp does not generate those memleaks.
Pcap privately shared.
