ST32F4 Systick_handler problem

Hey,

I am currently working on a project with an STM32F4 MCU. My board works fine until I try to put some output high and then a few seconds later low, this is done with starting a timer. After a couple of times for some reason my systick_handler doesn't get called again. Other timers are still being called. Does anyone have any idea what goes wrong? Or an idea how to locate the problem? Kind regards

Other interrupts with higher priority are entering, and they aren't being cleared, or fire too quickly, for other lower interrupts to get called at all?

You'll have to review your code, and the paths it takes, I can't do that.
