[rhegde2]

Describe the bug
PGadmin crashes with QueuePool limit overflow

Version of Helm and Kubernetes:

version: 1.15.4
appVersion: "7.4"
Kubernetes : OKE-1.27.2

Which chart:
PGAdmin4

What happened:

It fails with below error:

{"success":0,"errormsg":"QueuePool limit of size 5 overflow 10 reached, connection timed out, timeout 30.00 (Background on this error at: https://sqlalche.me/e/20/3o7r)","info":"","result":null,"data":null}

What you expected to happen:
It should run and accept the connections.

How to reproduce it (as minimally and precisely as possible):
Looks like a bug. It happens once every 2 weeks. May be some overflow. If I delete and create the pod then it works for next 2 weeks.

Anything else we need to know:

Does this also occurs with later pgAdmin4 versions?
