HI,

I am using Ansible - 2.1.0.0. part of my code is as below  
`

- shell: /etc/init.d/named restart  
when: (‘FAILED’ not in zoneconfig.stdout) and (‘neither’ not in zoneconfig.stdout) and (‘FAILED’ not in echofail.stdout) and (‘SUCCESSFUL’ in echopass.stdout\_lines) and (‘SUCCESSFUL’ in zoneconfig.stdout)  
ignore\_errors: True  
register: namedrestart

- debug: var=namedrestart.stdout\_lines  
when: (‘FAILED’ not in zoneconfig.stdout) and (‘neither’ not in zoneconfig.stdout) and (‘FAILED’ not in echofail.stdout) and (‘SUCCESSFUL’ in echopass.stdout\_lines) and (‘SUCCESSFUL’ in zoneconfig.stdout)  
ignore\_errors: True

- shell: /etc/init.d/named status  
when: (‘FAILED’ not in zoneconfig.stdout) and (‘neither’ not in zoneconfig.stdout) and (‘FAILED’ not in echofail.stdout) and (‘SUCCESSFUL’ in echopass.stdout\_lines) and (‘SUCCESSFUL’ in zoneconfig.stdout)  
ignore\_errors: True  
register: namedstatus

- debug: var=namedstatus.stdout\_lines  
when: (‘FAILED’ not in zoneconfig.stdout) and (‘neither’ not in zoneconfig.stdout) and (‘FAILED’ not in echofail.stdout) and (‘SUCCESSFUL’ in echopass.stdout\_lines) and (‘SUCCESSFUL’ in zoneconfig.stdout)  
ignore\_errors: True

`  
which in turns giving me error :

Kindly let me know how this can be resolved or is there any work around present.
