I have recently configured my FreePBX server. The server working is fine but randomly my server hangs out (freezes) completely with no input on terminal or on the web, after restarting the server it works fine and after some random time all starts again hanging or restarting. If someones have a similar problem please share the solution.
I suggest you install and run sysstat it takes a system ‘snapshot’ eveey 10 minutes , after the fact you can see what part got overloaded and when.
