[atlas] probe offline/lock up

I had an interesting alert yesterday, as my probe 54858 said it was offline.
I was unable to ping it from the router port it's directly connected to, but
did some some traffic on the port via the counters.  There was a fresh ARP
entry as well.

I power cycled it and it came back online.  I was then able to ping it via v4
after it DHCP'd it's address.  v6 pings were working to it's SLAAC address
too.  It has not gone offline now, but I am noticing pings on v4 are not
working at all again.  v6 seems unaffected.

Is this normal or is there a problem with my probe?  I've never really taken
this close of a look before, I'm unsure if it has an issue or if this is normal.

Thanks,
