[EP-tech] Error cannot allocate memory

Hi Lists,

Our repository sometimes having this error on the browser:

"Error calling df: Cannot allocate memory"

And checking on the log of the apache, I got this:

================

At the time of the error, tried to `df` using cli of eprints user, can give the disk free of the linux. 
Is there any way to debug more? Or the solution is just throw more RAM on the VM?

Eprints version: 3.3.15
OS: Linux Ubuntu 14.04
RAM: 1GB

Cheers,
