CNSserver does not start

I installed a CNSserver v1.3 on centos 6.7 64bits, but cnsserver services does not start, I executed the start script (/opt/cnsserver/scripts/ where I see this error:

[root@CNS scripts]# service cnsapache status
apache is running
[root@CNS scripts]# service cnspostgresql status
pg_ctl: server is running (PID: 3071)
/opt/cnsserver/stack/postgresql/bin/postgres "-D" "/opt/cnsserver/stack/postgresql/data"
[root@CNS scripts]# service cnsserver status
cnsserver dead but subsys locked

Is there any format error on database.json? 



I would love to be able to speak directly to your question. We had a similar issue not getitng CNS to work under a linux delpoyment. After toying around we tried the windows version, not great but it works well enough untill the new cloud platform permits onboarding ePMP clients.
