Pgpool restarts when tb-node scale up

[amir-hg]

Hi I use kubernetes v1.19.6 I can fully deploy thingsboard hybrid and high availability to kubernetes But when i scale up tb-node from 1 to 2 the pgpool instance became unhealthy after a while and restart the instance many times I do not think it is because of resources limitations because i could see that there is free resources. What do you suggest to solve this problem? Did i missed anything?
