OpenRefine Hangs On Start…

If you’re testing OpenRefine on things like Digital Ocean, use at least a 3GB server, ideally more.

If you use a 2GB server and default OpenRefine start settings, you may find it stalls on start and just hangs, particular if you are running it via a Docker container.

(I just wasted four, going on five, hours trying to debug what I thought were other issues, when all the time it was a poxy memory issue.)

So be warned: when testing Java apps in Docker containers / Docker Compose configurations, use max spec, not min spec machines.

I waste hours of my evenings and weekends on this sort of crap so you don’t have to… #ffs
