Description

hi, team:
I deployed Suricata v5.0.2 on an EC2 instance on AWS, use the analysis of VXLAN protocol to get DNS data ( Only mirrored DNS traffic )。An out-of-memory alarm event recently occurred on this machine.
This problem happens every day, I hope you guys can help me, I wonder if I need to add another server?

Sample from kern.log:
