I'm using a VPS.
It has 512 MB guaranteed Ram (2GB Burstable).
I'm running Voodoo chat on my server and now usage of my server resources are very high (MySQL), CPU usage is normal, but it has lots of simulation apache connections and MySQL connections, as a result when server getting lots of apache connections, it is restarting automatically.
I tuned MySQL server, but its not useful for this issue.
Now I think I need to host my chat database in another server for preventing interruption on my web site.
How can I do that, I need to host MySQL database on an another clustered server, but I've no money for an entire dedicated server.
