Pgpool works in Kubernetes with 3 replicas. Docker image 
pgpool/pgpool:4.2.2 is used.

One of the clients of Pgpool is Kong API Gateway. Periodically the 
follow error log message is appeared in Pgpool log:


pgmoon [10170] kong at kongdb |ERROR:  unable to read data from frontend
pgmoon [10170] kong at kongdb |DETAIL:  EOF encountered with frontend


pgmoon is a PostgreSQL client library that is used by Kong.

1. Why is this error happening?

2. How I can fix it?

3. How does this bug seriously affect the stability and performance of 

Thanks in advance.
