Luckally after a bit of research the solution is pretty easy to implement.

To resolve it in the short term run (as root): mount -t tmpfs shmfs -o size=1500m /dev/shm

To resolve it permanently change the line (as root) in /etc/fstab:

tmpfs /dev/shm tmpfs defaults 0 0

to read

tmpfs /dev/shm tmpfs size=1500m 0 0
