Using multiple instances within k8s deployment with zookeeper triggers panic and crashes pod

[stefan-chivu]

Hi, so I've been trying to use gnmi-gateway within a k8s cluster and deploy it with clustering using zookeeper.

For this configuration, everything is working fine:

As you can see here, the gateway acquires the lock for each target, syncs with them and starts sending requests and overall the deployment works fine:

Then, for testing purposes, I manually scaled up the gnmi-gateway deployment to two replicas, and started having issues with the second replica of the deployment, while the first one keeps running fine:

And then the pod enters in a crashloop.

I haven't figured out if I am missing some configuration when I traced the error and I was wondering what could be causing that panic.
