Rancher schedular unhealthy across multiple environments in one single host

Have created host with Ubuntu 16.04.4 LTS (with KVM) with docker version 17.12. and rancher server v1.6.14.

Now i have created around 4 environments pointing to the same host. Always, only two environments are activated. No stacks are created in none of the environments

Scheduler services are unhealthy in other 2 environments. Not able to know what could be the issue?
