when using redis servers with password authentication you may experience problems with shutting down server. it took sometimes up to 5 minutes to shut down server until i foudn out that redis was the problem.

the solution si simple: edit the /etc/init.d/redis_6379 file to “stop” section

add -a “yourredispassword”

CLIEXEC -p $REDISPORT shutdown

then your redis service will shutdown quickly
