Hello,

In our environment we received the error of our service that connects  
to Pgpool:

"HikariPool-1 - Connection is not available, request timed out after 
30012ms."

We run load test that generate 300 connections that send requests to 
database each 1-4 sec via Pgpool.

Most of connections was successed. But 3-4% was failed and service 
produced exception log which I mentioned above.

num_init_children = 200

max_pool = 4

I will be appreciate any idea what's going on.

Best wishes,

Nikola
