Sidekiq memory usage reset

Question

I have a Rails application that uses Sidekiq for a background process. To deploy this application, I use the capistrano, ubuntu and apache server. To start and restart Sidekiq, I use the capistrano-sidekiq gem. My problem is when Sidekiq is running, the amount of memory (RAM) used by Sidekiq is increasing. And when Sidekiq finished all the processes (workers), it holds a large amount of RAM and does not overwrite it.

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
ubuntu    2035 67.6 45.4 3630724 1838232 ?     Sl   10:03 133:59 sidekiq 3.5.0 my_app [0 of 25 busy]     

How to make Sidekiq in reset usable memory after workers finished their work?
