With current, 2.6.33-rc6, linux the default stack size changed from unlimited
to 8MB:
# > ulimit -s
8192

This makes NPTL allocate a 8MB stack for each thread that is created.
This breaks in our embedded system. Although this
can be fixed in our app I wonder if this is intentional?

When did this change from unlimited?

Sometime after 2.6.30 since that was the previous kernel we used, but I see
now that I read the wrong line. The stack size was 8MB in 2.6.30 too so
something else caused the high stack usage.

It's unlikely but this might be related
803bf5ec259941936262d10ecc84511b76a20921 (post rc7).  You'll also need
to grab this http://patchwork.kernel.org/patch/79365/.

I see, will try. Hope fully I will see an improvement. Thanks.
