Hello
I try to write twisted based daemon that work in multiple workers, like
this:
from twisted.internet import reactor;
from proxy import FASTCGIServerProxyFactory;
import os;
reactor.listenUNIX("/tmp/twisted-fcgi.sock", FASTCGIServerProxyFactory());
for i in xrange(3):
l_pid = os.fork();
if(l_pid == 0):
break;
reactor.run()
I creatae 4 wokers(by num of CPU cores). Im my test all ok, but when i
shutdown daemon i got follow error 3 times (because every worker try to
unlink sock file: /tmp/twisted-fcgi.sock):
Traceback (most recent call last):

line 134, in connectionLost
os.unlink(self.port)
exceptions.OSError: [Errno 2] No such file or directory:
'/tmp/twisted-fcgi.sock'
So my questions is How can i suppress this behaviour, so shutdown code
executes only once in main process?
