Linux OOM throws SIGTERM, but if I remember correctly JVM handles heap memory limits differently and throws OutOfMemoryError and eventually sends SIGINT.
Not sure what happened but the worker simply received a SIGTERM signal, so perhaps the daemon was terminated by someone or a parent process. Just my guess.
