Process CPU usage jumps to 100% without any reason?

[Kevin Chabot]

I am working on an application in c# that runs in the background.
All it does is monitor a value from a performance counter using a timer. It then draws these values in a chart

Now, this application works for a long time, sometimes even days. But sometimes it just freezes and the CPU usag
spikes to 100% for that process. I really don't understand why, and there seems to be no actual event that trigger
this. It looks like this problem occures more when I am using more CPU power during a long period of tim
(f.e. when compressing something). But even then, sometimes the program freezes and sometimes it keeps running
smooth at 0-2% usage..

Is there anyone that can give me an idea on how to solve this problem

I thank you for your time
Kind regards

Kevin,

I don't have an easy solutions. But I would write a text file log and see what's the last place it get's to before it goes off to never never land.

Hi

I've checked where the application starts to freeze
It happens right before my "Application.Doevents()" statement in my timer (100ms). After that
it keeps hanging there and CPU usage jumps to ~100%

Any ideas? :)
