Hi all,
I'm using xenomai  on kernel 2.6.29 on a powerpc based board.
I see that when I call : 
cat proc/meminfo
before pthread_create and after it there is a difference of 2MB in free memory , indicating that the thread is being allocated 2MB of ram (?) .

before :
MemTotal:       256868 kB
MemFree:        227624 kB

After :
MemTotal:       256868 kB
MemFree:        225632 kB

I am calling pthread_attr_setstacksize(&attr,8192)
before calling pthread_create so it shouldn't be the stack size .
Is this the expected memory consuption per thread ? 
if not, how can I reduce this ?

Thanks ,

Yigal Goldberger.
