Hi 👋

How are you attaching the agent? With [`apm-agent-attach-standalone.jar`](https://www.elastic.co/guide/en/apm/agent/java/current/setup-attach-cli.html)? What's the command you use?

From my guess is that the process ID `25421` either does not exist or is not a Java application. You can check that via `ps aux | grep <pid>`.
