I am running a Debian virtual server with Apache, PHP, MySQL. There is just 1 website with very low traffic running but the server very often (almost everyday) freezes and does not respond.
When this happens the server is unreachable from web browser or by SSH and I have to go to administration of my provider and perform server hard reset after this the server seems to work fine.
How can I find out what is causing the freezes?
