Observing broken pipe error while connecting to cloud sql

Hi Team,

We are observing broken pipe error while connecting to cloud sql from GKE network.

Here is the error logs from GKE pods.

{“hostname”:“http://localhost”,“level”:“error”,“msg”:"[Signin] a.db.Beginx() write tcp 10.x.x.x:54932-\u003e10.x.x.x:5432: write: broken pipe",“name”:“backend-API”,“time”:“2020-06-19T05:37:36Z”}

Please suggest on this issue.
