For me the most obvious approach is to put the probes behind a switch
that supports port mirroring and look at the actual traffic during this
period.

The fact that it happens to both probes at the same time makes it very
unlikely that it is a probe specific hardware problem.

I'm not aware of any bugs in the Linux kernel that would affect IPv4 and
IPv6 at the same time.

So the obvious next step is to check what actually goes over the wire.
