Hi, I am getting Stale Channels build up in my Freeswitch installation. We have a deployed a Dialer solution which is based on mod_callcenter, and a continuous stream of call are generated using Originate api command. As time progress the hung channels build increase and moment it reaches a threshold of 420+ of stale channels the entire site goes down. The Sip connections / extensions get disconnect and there is no means that they can get connected again. However, switch continues receive incoming calls, but extensions / agents sitting behind mod_callcenter are unable to answer calls. The only solution that I have is to restart the switch. I am using : Freeswitch 1.4 enabled with WebRTC support, SipmML5 based Sip Client and postgres as database. The solution is deployed on CentOS 6.6 64 bit. Regards, Naveen Khanna
