Ansible tower workflow

Hi

I am trying to follow the example given in the ansible tower workflow where using set_stats we can pass variable of previous playbook to new playbook. However i am getting the error in second playbook that the variable is not defined. My workflow template is correct as first job runs successfully.

What could be the reason or what all things I need to check.

Thanks,
Vinod

Hypothesis: Memcache is getting full and evicting entries.

Connect to memcache. From the Tower box: nc <memcache_container_name> 11211 then type stats and hit enter. You should see something like the below.

STAT pid 1
STAT uptime 34621
STAT time 1515457648

END

We are interested in the evictions

STAT evicted_unfetched 0
STAT evicted_active 0
STAT evictions 0

If the hypothesis is correct, there will be evictions.
