Samuel,

I did note those particulars metrics listed in your previous
correspondence but when I refer to network loads I am specifically
referencing data that show cases

- Volume of traffic that your network appliance is processes when the
gremlins show themselves
- Types of network services being offered by and traffic flowing through
the device at those particular times
- Looking at basic appliance hardware/OS system load readings vs network
traffic loads ratio graphs/data sets

From you dmesg, it appears that the hardware about which we are having
a conversation is a

Lanner Inc. NCA4010D

is this the case?

Finally, are you utilizing any of the 10Gbps Intel X710 SFP+ ports. As
Mr Stuart will bear witness, a number of months back he assisted me in
tracking down some resource utilization issues around a similar but
different 10Gbps Intel based ethernet controller.

Over the last 45 days our small team has begun rolling out 7.3 stable in
both our lab and across a few of our customers' infrastructures and have
yet to experience these issues but our upgrading efforts are still young.

Thank you much.
