Several days a week my openfire server is not in up. It’s down and i can’t access even admin panel. It shows **Timeout **when i trying to access admin panel and Connection failed when i trying to signin to my IM client. Please help me to server up. and what are the possible reason for that issue. My server is Apache (PHP/MySQL) VPS server and opensource installed using this (http://community.igniterealtime.org/message/204799) commands.
you may reach a resource limit. VPS servers tend to have such limits. See Linux Installation Guide
