It is hard to investigate without self contained test case. Is it possible for you to provide such that info?

Ideally self contained test cases. If you cannot provide them, pgpool debug log will be helpful.

Try to reproduce on test environment, right now leak issue have only on production. Also when services restart, it's free memory used it connection.

I have a suspicion that the quartz-scheduler is causing a leak
