Is it possible to try to reduce the memory footprint used when FME Server / Cloud is running idle? Ie have no jobs?
The starter instance of FME Cloud seems to use 2,7GB RAM when "no work is done" - is it possible to squeeze this down by 10%? 40%?
Might be a good internal hackathon.
The reason for doing so would be to make more memory available for the tasks themselves and avoid these frequent issues when you hit the roof on the lower-memory computers:
