suricata alerts for truenas scale SMB connections

[4o4rh]

I have my suricata in learning mode at the moment, and i see between;

• my PC = Kubuntu 22.10
• my NAS = TrueNAS-SCALE-22.12.1

I get the following two alerts in both directions consistently;
1:2210045 SURICATA STREAM Packet with invalid ack
1:2210029 SURICATA STREAM ESTABLISHED invalid ack
I get these alerts on both ports 445 and 43300

Is this something I can igore, or is there an underlying issue that should be dealt with?
