Max number of threads with NPTL

Hi

I was making som tests to see the maximum number of threads i could create
with the new linux thread library (NPTL). I had heard foks having up to
100 000 threads at the same time so i wanted to try for my self.

I used the 2.6.1 kernel with glibc with NPTL support, I used Sun JVM
v1.4.2 wich should have support for NPTL (I will make a try with the
newest blackdown JVM to night)

To my supprise i could not have more then ~3500 threads at the same time.
I got a OutOfMemoryException, but there was plenty of system memory left
(the JVM only ha about 10% of system physical memory).

I was wondering if someone had any experience in this field, perhaps know
som build in limits of any kind (OS or JVM) that could be tweeked.

Best regards
Daniel
