CPU usage up to 100% and crashing PCs

Since the last update (yesterday) the timetracker client has a strange behaviour.

Every time you start the timetracker, it uses a huge portion of the CPU. When you stop the tracker, the CPU usage stays on the same level. You start tracking again, it uses an additional portion of the CPU. Do this 3-4 times and the CPU usage is up to 100%. Eventually, the PC freezes/crashes.

We can reproduce this on several different PCs/Laptops. All of them run Windows 10 64bit. In my case its a Windows 10 Enterprise N, Version 1703, OS Build 15063.483. I only use Outlook, Chrome and Slack.

It seems like this bevahiour only appears after the "second track". If you start the tracker on the first Work Item, it looks good. Stop tracking, start again, and this is what happens:

Do this 3-4 times, and this is what you get:

Here is the Task Manager from another Laptop:

    I have been seeing this issue lately as well, ever since I started using my new Windows 10 machine. The OP is correct that pressing start / stop repeatedly on a task is the easiest way to reproduce this error:

    This has been a problem for me (and the rest of our team) for the last day or two. I know I received a client update yesterday or the day before, behavior has been observed since the update.

    Where can I find the hotfix that should fix this problem. I can't track my work at all as it uses up to 100% CPU, same as per above issues. I am running Windows 10 Pro 1709 build 16229.15.

    Assistance will be greatly appreciated.

    Thank you for the response. 

    I am however having difficulty installing the update. If I look at the appdata the new version is there, yet the application running stay the old version. Tried uninstalling and deleting all history, folders etc. Our TFS is 3.0.4, is this maybe why I can update the client version?

    Client version even after update install etc

    Windows client always syncs its version with paired server. So it does not matter what version you download it will always sync it on start with server. 

    I can recommend you to update Timetracker on your server side if that is possible in your environment.

    Hi Maxim,

    Can you please point us to the version of Time Tracker in which this issue was fixed ?

    We are currently experiencing similar symptoms with version 3.1.1.12107 but would prefer not to upgrade to the latest version.

    Thanks in advance.

    Hi Maxim,

    Thanks for the info ! We will deploy the version you mentioned as soon as possible.

    We are currently using the latest version ever with our VSTS instance, and we’re still experiencing a few issues (which were reported and are currently being investigated). Besides that we can see that updates are still somewhat frequent with the latest version. It's far from being a show-stopper, but for our on-premises instances we prefer to work with more stable versions. This causes our team less overhead, since we are responsible for the administration and troubleshooting of the tool.

    Anyway thanks for the support, much appreciated !
