Hi Jose,

To be honest I'm not sure what all different memory things mean, but I 
checked it out: they are not, Cached stays the same and MemFree 
decreases. However, I discovered that it only happens when the rtai_* 
modules have been unloaded and are reloaded again. So it seems its not 
the LXRT task (preempt in this case) that leaves the memory occupied, 
but one of the rtai_*.ko modules. Any ideas about how I could try to 
find the reason?
