   ### Fluss version
   
   0.8.0 (latest release)
   
   ### Please describe the bug 🐞
   
   If the server's shutdown hook does not complete within 10 seconds, the service will be forced to kill. The reason is that the `fluss-daemon.sh` set a 10-second timeout before forcibly killing the entire service:
   
   ```
   function guaranteed_kill {
     to_stop_pid=$1
     daemon=$2
   
     # send sigterm for graceful shutdown
     kill $to_stop_pid
     # if timeout exists, use it
     if command -v timeout &> /dev/null ; then
       # wait 10 seconds for process to stop. By default, Fluss kills the JVM 5 seconds after sigterm.
       timeout 10 tail --pid=$to_stop_pid -f /dev/null &> /dev/null
       if [ "$?" -eq 124 ]; then
         echo "Daemon $daemon didn't stop within 10 seconds. Killing it."
         # send sigkill
         kill -9 $to_stop_pid
       fi
     fi
   }
   ```
