digicm 16 kcore / 100%

I’ve been trying to get our term server work to no avail. I see that / dir is 100% and kcore under /proc is the largest file. I tried to delete it but operation not permitted. Also rebooted term but it is still there. What else could i do? I’m new to this and just inherited this device.
