Too many connection errors while connecting to InnoDB Cluster running on EKS

[Vyaghri Kasibhatla]

Hi All,

We have installed mysql-operator and mysql-innodbcluster on EKS using the instructions provided in the documentation:

https://dev.mysql.com/doc/mysql-operator/en/mysql-operator-innodbcluster.html.

After the installation is successful, we are updating the mysql service to a LoadBalancer type and trying to access the cluster using the LB Name and port 3306.

It worked fine initially. But after sometime it started giving these errors:

ERROR 1129 (HY000): Too many connection errors from xxxx:xxxx

I tried increasing the maxconnections, flushing the hosts etc. Nothing helped.
I bounced the pods on the statefulset as well.

Any thoughts on what could be going wrong ?
