Ccccam 2.0.9 second client problem

Hello gurus,

could you please give me a help on the following:

I am sharing an Iderdo v5 card in my dbox500 using Gemini v4.50 and Cccam 2.0.9 as a server and client.One of my clients with the same box (Gemini & Cccam 2.0.9 client) works fine and non-stop.But when a second client try to connect (same machine and configuration) after 10-15 minutes the picture is freezed and probably a restart will recover the client but sometimes restart is not enough.
Could be a problem of my Cccam server supported clients,should i configure something specific in my Cccam.cfg for the number of my clients?
Will be better to share my card using NewCS server.(I am not sure the i know how i will configure NewCS.xml file for sharing ...but anyway..).

Any suggestions??

Thanks
