RAC Daemons still running after stopping cluster

 Hello experts,

i have a question on below RAC background process ,

[root@]# ps -ef |grep d.bin|grep -v root

grid     31400     1  0 11:29 ?        00:00:15 /u01/app/11.2.0.4/grid/bin/oraagent.bin

grid     31413     1  0 11:29 ?        00:00:00 /u01/app/11.2.0.4/grid/bin/mdnsd.bin

grid     31506     1  0 11:29 ?        00:00:03 /u01/app/11.2.0.4/grid/bin/gpnpd.bin

grid     31547     1  0 11:29 ?        00:00:15 /u01/app/11.2.0.4/grid/bin/gipcd.bin

above Daemons are still running after stopping the cluster (crsctl stop cluster -all). is this expected behavior ?

please advice.

my Envirionment :

system arch : x86-64

OS  : RHEL 6.4

grid version  : 11.2.0.4 RAC
