Hello, I am working on a Zope product that throws data into a queue that is monitored by a number (3) of producers. Producers can talk to Corba objects. I use omniOrb for this. Producers take out data from the outqueue and send it to other Corba objects. This is the basic setup: class SIPConnector(SimpleItem): """Connector class""" def __init__(self, id, title): self.id = id self.title = title self.n = 3 # number of producers def initConnectionPool(self): self._v_outqueue = Queue.Queue() for i in range(self.n): id = 'tc' + str(i) tp = SIPProducer(id) thread.start_new_thread(self.runProducer, (tc, self._v_outqueue,)) def post(self, sid, to, msg): self._v_outqueue.put(sid, to, msg) def runProducer(self, tp, oq): # connect to Corba dispatcher tp.orb, tp.cmf = tp._connect() while 1: try: msg = oq.get(0) print msg tp..cmf.xmit(msg) except Queue.Empty: time.sleep(0.05) class SIPProducer(CorbaBaseClass): def __init__(self, id): self.id = id This basically works. However, if I put msg's in the queue with the post method from a page template, and I do this a couple of times, quickly, I get an attribute error on self._v_inqueue. It is somehow gets lost. Does anyone know what I am doing wrong here? What happened to the 'lost' queue? Cheers, Joost -- Brain, v.
