We're running QB 7.0.31 with PostgreSQL database. The login role had a limit of 50 connections. The QB db pool has a max size of 50.
We've seen a lot of log lines on DB side like:
FATAL: too many connections for role "quickbuild"
because of this also builds failed. I increased the login role limit to 70 and it still fails. And always at around the same time: When the QB backup is running.
Now I'm wondering if QB tries to open more than the configured connections to the database during the backup process?
