After going through the HCL Sametime 11 FP1 Community Server logs, I found the following error:
CLMONGO, ChatResource::readSrvMsgFlags ERROR: empty UCM_LOCAL_IP
Like in the Screenshot bellow:
I am not sure if this error affects the any functionality of the System, but to solve it I simply added the “UCM_LOCAL_IP” parameter to the sametime.ini file, inside the “[Connectivity]” section. The Value of the “UCM_LOCAL_IP” parameter should be set to the local IP Address of the Sametime Community Server.
I hope this helps.
