APIResponse received a response which is not a valid JSON

Hello All:

While testing demo-playbook.yml, I get the following error. Any ideas as to why the response is invalid? 

api status -s outout attached

[root@Ansible-Cent Playbooks]# ansible-playbook -C demo-playbook.yml

to retry, use: --limit @/root/cpAnsible/Playbooks/demo-playbook.retry

From the api status output, it looks like the API server crashed for some reason.

If I had to guess, it's because you've configured this VM with only 4GB of RAM.

The stated minimum in the release notes for R80.20.M2 is 6GB of RAM.

I highly recommend more. 

In my own lab, my management VM has 16GB of RAM allocated (but I'm also using SmartEvent).

Thanks Dameon:

Your guess is right, the demo mgr was setup with 4 GB ram.

While, I didn't notice spike in memory on Manager when playbook was run but  after upgrading the memory to 8 GB, the error didn't occur.

Hello,

can someone please, give the commande line to upgrade max_ram in checkpoint management server,

Thanks

We're talking about adding RAM to the appliance or VM.
That is not something you can do over a command line.

[dassouka]

thanks for feedback,

actualy my appliance already have 16G of RAM, but my i still getting errors when calling checkpoint API using Ansible.

 something like  NGM_CPM_MAX_HEAP

this is the error i get 

fatal: [localhost]: FAILED! => {"changed": false, "msg": "Command 'add-service-tcp {u'name': u'tcp_1005', u'port': u'1005'}' failed with error message: APIResponse received a response which is not a valid JSON.. All changes are discarded and the session is invalidated."}

That error usually means the API server is not enabled.
Make sure it's enabled and access is allowed from your IP address.
