Public bug reported:
Since I've updated my laptop to Ubuntu MATE 17.04, I notice ping
sometimes gets into a runaway mode.
I'm on a shaky Wi-Fi so to monitor connectivity I usually have a long
running ping command against google's DNS server:
> ping -s16 8.8.4.4
Often, after leaving it for a while, I notice screaming vents and htop
then shows the ping process consuming 100% of one CPU. It will stay like
that until ping is killed.
I'm not sure how to troubleshoot this issue, can someone recommend a
protocol?
