[Freeswitch-users] MOD_CALLCENTER become unload and unknown while freeswitch is still running

Hi, Currently, I faced a very strange issue that 1) After several days of FreeSWITCH running, I could not connect to its CLI at all. But Freeswitch is still working as it is. I have to tail the log file to debug this issue. 2) When the issue (1) happens, the application *callcenter *is unknown and therefore the callcenter failed. FS version: 1.6 Any help would be appreciated. Thank you in advance. Best regards, Chhorm Chhatra
