I have website which has a chat engine written in Strophe and in a XMPP server, now we use openfire however openfire get crashed many times, openfire experts says that its goto to do with the server environment problem rather than the coding it self. Even restarting the openfire dont fix the problem. I results in 503 error in the sever, which is running nginx and cpanel. Server hits over 4,000+ users per day, and its 8 quad core server with 16 MB RAM.
1. Identify what is the cause for this problem ie Openfire,Nginx, MySQL
2. Make sure Openfire runs smoothly and chat server doesnt fails
3. Optimized the server environment for the users
see the questions i asked about this in the stack overflow,
