Hi Jean-Paul
Smarthead :)
You were right. I quickly ripped out the forking code in daemonize in _twistd_unix - et voila: It runs nicely.
Now that's one of the points where it'd be great to know more about the inner workings of TM. If i did, I probably could just open them sockets (fire up the whole event engine) _after_ forking, i.e. in the child process.
As it is, though, (me newbie, gazing unsmartly at TM *g) I'd rather not touch it.
Thanks for having your Synapses fire ;)
