Redmine. Memory leak?

Question

Redmine

Hello!
Does anyone know how to overcome the terrible memory leak in Redmine (under Ubuntu)
It is very unpleasant to see this picture:

Answer 1

Is this a leak? Ruby eats about as much at startup, and further down the line, it can slightly reduce / increase the amount of memory used. It works for me for months (from update to redmine update) with such values.

Answer 2

The swap is at zero, so everything is fine, what is the leak then?
