what is runtime broker, and why does it use so much memory?

The tile application, "The Time", has been fixed and updated, but my Runtime Broker still had a memory leak and the Runtime Broker was still chewing up to 500meg or even to 1 gig of RAM each session.  Eventually my computer would kind of give-out, and I would have to reboot periodically.  After awhile, each session, the hard drive started thrashing continuously - probably the pagefile and friends getting extra duty, as I only have 4 gig of real RAM.

I eventually traced the problem to an app called "Clocktime", from a German company.  Once I uninstalled that, the Runtime Broker was no longer being reported as the most memory-hogging program in Task Manager.  Now with "Clocktime" gone, instead of leaking 1 gig of ram a day, the Runtime Broker is back to normal and has to be searched for in the Task Manager instead of rising to the top of memory consumption.

So the Runtime Broker memory leak is real, and it is usually one of the "clock" apps running in the Lock Screen background that is causing the leak.

Hi Faragondk,

Are you saying you are hitting a memory leak problem?  If so, I'm going to give this a shot but no guarantees I can fix anything. 

What modern UI applications are you running?  Please provide a list containing the exact name and author of the app.

And which version of Windows 8 are you running?

To get at the root of the problem, run the apps and, with the help of Task Manager, write down how much memory is consumed by each one.  Then, wait 30-60 min, and again write down the amount of memory consumed by each one.  The ones whose memory consumption is larger would be suspect.

Thanks,

I'm not running this clock app, and the Developer behind the time app has explained the memory leak in detail, so there should be a fix coming.

My Runtime broker uses between 1-2 GB of memory, but has been seen to use even more.

I don't even use the new start screen much.

This problem is most prevalent if you are using some clock app from the store. Uninstalling it nailed it for me.

This is a real problem,.. my PC is not infected,.. and Win 8 was clean installed only a month ago. This needs to be fixed ASAP!!! What is the soloution.
