Description

Rules like these (from datasets-09-load):

alert http any any -> any any (ip.dst; dataset:isset,ipv4-list,type ipv4,load datasets-ipv4.csv; flow:established,to_server; sid:1;)
alert http any any -> any any (ip.src; dataset:isset,ipv4-list,type ipv4,load datasets-ipv4.csv; flow:established,to_server; sid:2;)
alert http any any -> any any (ip.dst; dataset:isset,ip-list,type ip,load datasets-ip.csv; flow:established,to_server; sid:3;)

Will trigger as well on flow timeout packets.

@Victor Julien do you have an example for that so I can try to reproduce and debug it?
