[Freeswitch-users] CS_INIT,,,,,,,,DOWN

Hi, I’m a long time user with Freeswitch, however I’m getting a strange issue I never found over past years. If I take a look at fs_cli console and look at “show calls” result I can see a great list of calls with state: CS_INIT,,,,,,,,DOWN This call count is increasing and is eating hardware resources until CPU / MEMORY leave the server unresponsive… How to clear these “zombie calls?” Is there an explaination for calls being frozen with this state? Just to clarify I’m using FS 1.6.20 git 43a9fe with Debian 8 ( I know it’s old, but can’t update for policy reason.. ) Thank you for your help, FS rocks! Max
