Too much memory usage

[alert (Alessandro Pisa)]

I usually add a job in my crontab to restart the instances periodically.
Weekly, nightly or whenever is needed.

I know other people disagree with this approach but it works for me.

To have a complete picture I suggest you to have a look to:

Is auto stop/restart of site still needed to prevent memory build up

For my plone 3/4 sites I use to have, I had a crontab job that ran periodically to stop/restart site because Plone, especially 3, was a memory hog. Is this practice still considered good practice for plone 5? thanks
