Thanks, I bumped up the memory request when it starts and that seems to have resolved the problem! Also I hadn't realized that you need to repeat the same commands whenever you run webservice start - I thought it retained the previous settings, but it looks like you have to be specific each time or it falls back on the old defaults?
