Makes sense. According to other comments in the thread [1] the page requests a wasm heap of 1.25 GB (...hopefully unnecessarily!), while the iPhone SE has 2GB of RAM total, so it's easy to imagine that the remaining amount isn't enough for both other allocations in Safari and other processes. I tested it on my iPhone X which has 3GB of RAM – not that much more, but apparently enough. [1] https://news.ycombinator.com/item?id=18983109 https://news.ycombinator.com/item?id=18983109
