How to increase the amount of available memory?

If your test suite runs out of memory even after stopping non essential services, we’d suggest creating a swap file (which implies sacrificing a certain amount of disk space), by adding:

sudo swapoff -a
sudo dd if=/dev/zero of=/swapfile bs=1M count=1024
sudo mkswap /swapfile
sudo swapon /swapfile

These commands will create a 1GB swap file. If you’d like to create a larger swap file, you’d need to increase the count parameter. The Semaphore Classic environment runs in a RAMDisk, so the performance overhead of a swap file should be minimal.
