LinuxThreads - Stack size and Memory consumption

[AmitDanziger]

Hi everyone,
(I've already posted this one on the general forum, but this is probably more suitable).
I'm working with LinuxThreads (glibc2.3) on an Embedded system (MontaVista 3.1 distribution).
I have several problems with the threads memory consumption:

1. Is there an option to limit the stack size?
   If I understand correctly, in LinuxThreads, regardless of the scheduling policy, the stack size of each thread starts as 4KB and grows up to 2MB.
   Is that true?
   Is there a mode for a static non-growing stack?
2. How do I measure the actual memory consumption of each thread?
   Using ps/top/proc is problematic since it does not show the actual memory usage - because of the "copy on write principle".
   Any idea?

For the second problem, try with a profiler similar to valgrind. It usually throws a lot of information and deals fine with threads.

For the first question, maybe you want to send it to kernelnewbies.

Best Regards
