Question about socket syscall in release 6.2
I have found some weird behavior about the socket system call in freebsd release 6.2. The problem appears if I try to open more sockets than the ulimits allows: the socket system call gets blocked instead of returning an EMFILE error. This only happens to me in release 6.2 ( I tested in 7.0 but it works fine). The following python script is what I have used to reproduce the issue: import os import socket from random import randint import sys socketAddress = (127.0.0.1, randint(2, 3)) s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) s.bind(socketAddress) s.listen(1) socketList = [] child = -1 for i in range(1): child = os.fork() if (child): clientCon, address = s.accept() socketList.append(clientCon) os.waitpid(0, os.WNOHANG) else: print child %d % i clientSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) if (clientSocket==-1): print(client socket error) err = clientSocket.connect(socketAddress) if (err==-1): print(client connect error) break Is there something I'm missing ? Can someone shed me some light about this ? Thanks in advance.
