Mine's a Clojure app and I'm running it via `java -Xmx180m -Xms180m` and my fly.toml has a kill_timeout of 15 and in services.tcp_checks I now have interval 25000 and timeout 9000 - but as I wrote, it's a very basic app, anything JVM on 256MB has always (even years before fly.io) been hit or miss, sadly. Good luck!
