[EP-tech] Error cannot allocate memory

[bbuuddiiww at gmail.com (Budiwijaya)]

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,
Budiwijaya
