redis memory increasing linearly

[Francesco Giuseppe Toffoli]

Hi everybody,
since a coupe of weeks the memory used by Redis in increasing linearly, 
continuosly.
We are a bit worried as also after a Redis server restart the situation 
is the same (the RAM taken is equal before and after the restart).
I would exclude the issued has been caused by a configuration change, 
the issue started on 20 November at 11:44PM when nobody was working on 
bischeck.
I'm enabling logs in order to see if there is something wrong.

In the meanwhile does anyone have a suggestion on how to proceed?
Upgrading to Redis 4.0 (stable) can be done maintaining the 
retro-compatibility with Bischeck? (we have Redis 2.8.23)


As a workaround I was thinking to enable the Redis option 'maxmemory' 
with the 'maxmemory policy': about this last option, as we need all keys 
to be maintained on database, does anyone know as can be set? (I've read 
something about key eviction but i still don't have any clear idea).


Regards,
Francesco
