Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, hopefully a simple question to answer: I get "cannot fork" messages on my machine running some 20000 processes and threads (1 master proc, 3 threads), where each (master) process opens a socket and does IP traffic over it. Although there is plenty of memory left (4GB box, 2GB used, 0 swap), I get "cannot fork - out of memory" when trying to increase the number of procs. (If none of the procs does IP, I can start more [of course?!].) Anything I can do to increase the number of active processes using IP? Any kernel paramter, limit, sizing? Many thanks for the help in advance!
