Seems to happen during high traffic parts of the day, I have talked to networking and they are saying it is the kiosk. I have replaced everything and it still occurs. Has anyone else seen this before on their campus?

Hi Mike,
This happens when a large amount of traffic is making its way to the NIC of the Omega. If there is multicasting in the environment this can be a cause.
1. The line below indicates that the this message is received because the nf_conntrack kernel maximum number assigned value gets reached. The common reason for that is a heavy traffic passing by the device or being aimed at the device.
"user.warn kernel: nf_conntrack: table full, dropping packet."
2. The below line is the result of the above. In Linux, the log messages from "tcp" spill over to the "kernel" thus you see it logged by the kernel.
"user.warn kernel: __ratelimit: 3507 callbacks suppressed"
Unfortunately you will need to use a packet capture tool of some nature to see where the packets the device receives are originating from.
Regards,
Jeff Geller
