2012 SP1, server crashes, possible cause VSS?

Hi everybody.

I'm new to SCDPM in genreral, and i'm having a few issues with the server.
In short, i'm going to list my setup underneath.

Physical HP server, Windows server 2008 R2, SCDPM 2012 SP1, 32gb ram, 279gb system drive (at the moment 189gb free), 32tb DAS with 27tb raid 50 partition.
All of the sudden our server becomes unresponsive after working perfectly for a few months, so i had to Cold boot it.
Now the server is up and running, but i have some errors in my event log saying that the system drive is full, even though it is not.
I suspect some shadow copies is messing stuff up.

Please tell if you need more information to analyse this problem.
Thanks in advance :-)
