[PERDITION-USERS] cyrus perdtion , connections not dying

I have a 40k user cyrus server , and I am trying to scale up by trying to add a perdition server infront of this server so that we can add more servers ( Both servers dell 2950 with 8GB RAM ) But the problem I have the moment I install a perdition server is that , the number of pop connections do not seem to reduce at all once started. I had 10 connections in morning and with 15 minutes the number of connections went to 3000. And on the real server the connections are all full Usually we have around 700k simultaneous pop connections on the real servers now with perdition we have 3000+ connections How do I get perdition close connections quickly
