Description Patrick Tasse CLA 2011-11-30 16:40:49 EST 
In the TimeChartView DecorateThread private class, a TmfContext is created for small amounts of work. When possible the context is reused, but in some cases the context is replaced and the old context is left for garbage collection.

In some extensions, the TmfContext can own limited system resources such as a file descriptor. If the DecorateThread uses too many context in a short time, the system can run out of file descriptors before the garbage collector has time to dispose of the context.

The solution is to dispose the old context whenever it is replaced by a new one, and dispose the last context at the end of the thread execution.
