UniFi's Java process crashes during shutdown (Spring context race condition) leaving mongod orphaned in the cgroup. The upstream module sets KillSignal=SIGCONT so systemd won't interrupt the graceful shutdown, but with the default KillMode=control-group this means mongod also only gets SIGCONT (a no-op) and sits there until the 5-minute timeout triggers SIGKILL. Switch to KillMode=mixed so the main Java process still gets the harmless SIGCONT while mongod gets a proper SIGTERM for a clean database shutdown.
