Hi! I would like to know why spark freeze for about 5 minutes after i login on openfire server. I tried version 2.0.8 and 2.5.3 but the problem was the same. When i login on openfire with spark, the roster appear to me immediately with all user registered, but it takes about 5 minutes to give me again control over client and let me write down messages to users. Can you give me sono advice on how to solve this?
