Heya,

First, I suggest you find the source of those connections. Are they connections that were not closed properly, or do you have a lot of connections to your application?

If it’s the first, until you fix the problem, these connections will continue to appear and stay open. Only after that is done, you can be considered looking at the connections.

If your application has a lot of traffic, thus creating a lot of DB connections, then you’ll need to consider upgrading.

As for the connections they should clear automatically once they timeout.
