There was a crash and then mtp-server restarting in loop, which caused it to show on top:

Title:
  MTP looping between start and stopping causing constant ~10% cpu load

Status in mtp package in Ubuntu:
  Confirmed

Bug description:
  When unplugged from USB, I notice when running $ top that init, dbus-
  daemon, mpdecision are constantly using in total ~10% CPU.

  The steps I have performed to cause this:
  1) Ensure the device is off
  2) Plug a USB cable into the device and a computer with MTP support
  3) Boot the device
  4) Unlock the device, run the terminal and the command $ top
  5) Wait until the CPU settles, then unplug the USB cable
  6) Now notice that init, dbus-daemon, mpdecision start using ~10% CPU

  This is the output from running dbus-monitor [0]

  Note that when I plugged my device into a PC the CPU usage reduced
  back to normal, but then when I unplugged it again it increased back
  to ~10% again.
