Just got a problem on Fedora Core 1 box, I can only open 256
threads per process. But on my former Redhat 8.0, I can open 1533 threads per
process. From post http://www.redhat.com/archives/fedora-list/2003-December/msg04136.html,
I still can not quite understand, Since I can only use 2GB
stack space. (256*8MB). Not 3GB. The source of the thread-testing C file is from website http://www.linuxquestions.org/questions/showthread.php?s=&threadid=173680.
Any other easy ways to change system-wide threading limit? At
least from Fedora Core 1’s 256 to Redhat 8.0’s 1533? Thanks A lot. --Guolin Cheng bash-2.05b$ ulimit -a core file size
