Boot your server into rescue-pro and run the diagnostic checks on the memory, CPU and discs to rule out hardware failure, after that you may need to try and pin it down to a specific piece of software running on your system.

http://help.ovh.co.uk/RescueMode has a simple guide

So my server after 8 months of stability has decided to restart itself randomly crashing all my processes. Does anyone know where i can check as to what the problem is and what exactly am i looking for?

Rrunning: 64 bit debian 6.0 with netboot set to kernel from ovh.
