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
