We have a product in the field where we are seeing io-graphics become a CPU hog over time.

In this product we have a fixed number of applications that are running under Photon.
The system is "stable" in the sense that the number of applications, and what they are doing, essentially doesn't change
.

However we are seeing that over time (a period of weeks) the CPU usage of the system increases to the point where it 
becomes un-usable and needs to be re-booted. Typically the system will be stable for many days/weeks and then the CPU 
usage will begin to increase over a period of days. Once it starts increasing it takes a couple of days to become 
unusable.

Our initial analysis shows that when the CPU usage starts increasing, the main culprit is actually io-graphics. It goes 
from using negligible amounts of CPU to 10%,20%,30% of the CPU or more. None of our other processes show any increase in
 memory or CPU usage.

We are running 6.3.2A on x86 (PC Platform).

I know that we haven't given enough information for anyone to be able to actually help us track this down, but we do 
have the following questions:

- Has anyone seen anything similar to this before?
- What additional information do we need to capture to try to isolate this problem, and how do we capture it?
- Any other hints for how to get to the bottom of this?


Thanks in advance for any ideas.
