We have been running Openfire on CentOS 5 for about 7 years. Since upgrading to 3.10.0 our server will stop responding to new connections after about 3 days.
We have a very small install with about 15 clients at peak time. For the first couple days after a reboot all clients can connect without issue. After about 3 days existing connections work but new connections fail. So as long as everyone stays connected they are fine. Restarting openfire clears the problem.
Also, when the server stops responding to new clients, the "Client Sessions" tab will not load in the web interface. I think most of the other pages work fine.
Other details:
- Centos 5 has all the latest updates
- Most users use Psi as a client
- We use LDAP to authenticate to our Zimbra mail system
