SysTick now CRAWLING - K22F

So I have an OSA instance of FreeRTOS ticking off the SysTick at 100 Hz. That normally works just fine, but every now and then the RTOS related process appear to come to a stop. When I capture what is happening, the SysTick appears to be firing once every 2-3 seconds or so, rather than at 100 Hz.


I thought it might have something to do with interrupts being disabled or some such, but other interrupts run just fine.


I don't even know where to being looking at this. EmbSysReg doesn't include SysTick and the Registers in the debug window don't either.


Any suggestions on where to start would be greatly appreciated.
