Hi Guys,

I met a strange issue "shared connection closed", googled but don't find any solution or workaround.

when the issue happened , the network is ok , why ssh connection closed ?

My verion is as following.

[root@director ~]# ansible --version
ansible 1.9.4
configured module search path = None
[root@director ~]# uname -a
Linux director.vepc.mnc066.mcc260.3gppnetwork.org 3.10.0-514.el7.x86_64 #1 SMP Wed Oct 19 11:24:13 EDT 2016 x86_64 x86_64 x86_64 GNU/Linux
[root@director ~]#

[root@director restart-service-overcloud]# vim site.yml
[root@director restart-service-overcloud]# ansible-playbook site.yml
