Here is my problem.
Linux (red hat at least) has limits on the number of threads that can be
a process ... apparently this is 1024 threads.
I have a test program called TestThreads. When I run this program it creates
, each thread sleeps 60 seconds and then finishes. I cannot get past a
thread count of
1024 . I will be needing a lot more threads than that for my application to
On windows I can run the program from the console and it goes up to 7988
threads so it looks
to my boss like linux can't scale :( this is not the view of Linux that I
The problem IMHO is that the glib library has been compiled with the
#define PTHREAD_THREADS_MAX 1024
in the file
I have modified this and uped the number to 8192.
#define PTHREAD_THREADS_MAX 8192
I have then configured it with
./configure --enable-add-ons --prefix=/usr
and did a make and make install ... (this took about 2 hours to run)
I then tried out my thread testing program again.
Same thing... it gets to 1018 threads and then produces an out of memory
I can run 4 instances of it at the same time in four different consoles and
console 1 664
console 2 1018
console 3 1017
console 4 917
This is wierd ... anyone got any ideas ?
PS: I've been in google hell for a couple of days so no links to volcano ...
