ENV:

service log:
2018-08-24 11:10:53.179 2627349 WARNING neutron.services.logapi.drivers.openvswitch.ovs_firewall_log [-] Unknown cookie=2664476845653012007 packet_in pkt=ethernet(dst='fa:16:3e:73:9f:a3',ethertype=2048,src='fa:16:3e:81:02:32'), ipv4(csum=39526,dst='192.168.111.5',flags=2,header_length=5,identification=50582,offset=0,option=None,proto=6,src='172.16.0.1',tos=0,total_length=60,ttl=63,version=4), tcp(ack=0,bits=2,csum=60919,dst_port=22,offset=10,option=[TCPOptionMaximumSegmentSize(kind=2,length=4,max_seg_size=1460), TCPOptionSACKPermitted(kind=4,length=2), TCPOptionTimestamps(kind=8,length=10,ts_ecr=0,ts_val=3048195896), TCPOptionNoOperation(kind=1,length=1), TCPOptionWindowScale(kind=3,length=3,shift_cnt=7)],seq=3571909294,src_port=47012,urgent=0,window_size=29200): CookieNotFound: Cookie 2664476845653012007 could not be found.

How to reproduce:
1. add ACCEPT log to port and security group
2. ssh to the server <-- here you can see the ACCEPT LOG
3. disconnect the ssh, and ssh again.
Then the resource log has the WARNING CookieNotFound.

So I think code is basiclly same to the master, I think we can reproduce this in master branch.

Hi @LIU Yulong,

I cannot reproduce this bug. Could you provide the reproducing steps? For example, how did you create the logging resource. If you delete and re-create the logging resource and VM, did you still see the error?

[Hongbin Lu (hongbin.lu)]

I try both master and stable/queens but couldn't reproduce the error. I saw the "ACCEPT" actions were logged without a problem. To further traige this bug, we need more information about how to reproduce the bug.

[Hongbin Lu (hongbin.lu)]

I am going to mark this bug as "incomplete". Please feel free to reset the status as "new" once the reproducing steps are provided.

Disappear from the test env, please retore this if anyone meets this again.
