Title:
  Long-running ping command leads to 100% CPU usage

Status in iputils package in Ubuntu:
  Confirmed

Bug description:
  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?
