How do I begin to diagnose and fix indicator-datetime-service using 100% CPU and 90+% memory in 16.10?

The high usage starts immediately after boot, pauses for 2-3 seconds every minute or so but otherwise uses the resources to the extent that the computer is useless. I can get my system back temporarily by issuing a killall unity-panel-service but that comes with some usability overhead and isn't a solution.

  1. This happened to me on Ubuntu 17.10. The cause of the problem for me was that the evolution data server was trying to sync with Google calendar events and somehow caused a memory leak.

    Before doing anything, you may need to stop the indicator datetime service temporarily to get your computer in a usable state. Here's how:

    1. Open up System Monitor
    2. Sort services by the highest CPU or Memory consumption
    3. indicator datetime service should show up at the top
    4. Right click on it and select stop process.

    Now we need to disable the Google calendar sync.

    Here's how to do it:

    1. Open up Calendar
    2. From the menu, select calendar > Calendars
    3. From online accounts, select Google (or maybe it's another one for you)
    4. Disable calendar sync for the online account

    I actually just removed the online account entirely and when I rebooted the problem was gone. Hope this helps.

    A clue on how to solve this is here. Here's the full bug report.

    From the comments...

    Everything appears to work properly in the Guest account.

    Possibility that something in the primary user's account is causing the problem. Suggest that they temporarily disable some Startup Applications to see if that fixes the problem.

    User disabled a clock/calendar indicator, and so far, it's all running good.
