volumes configuration

Description of problem:

We have a production system with a glusterfs working as replication system
between two servers. Replication directory has 2Gb total size and contains near
20-30 files. 
We noticed that glusterfsd process memory consumption permanently growth on
both servers on 30Mb/day. Memory increase occurs irregularly (I mean memory can
be constant for 3 hours but then abrutply 
increase on 16 Megabytes). We are working with 3.8.8-1 release, but have
checked that issue is still reprodusible on the latest glusterfs 3.13 release.
Our operation system is Debian Jessie. I can provide any log or debug info that
you need to fix this issue. Just tell me what I need to provide.

Version-Release number of selected component (if applicable):3.13


How reproducible:


Steps to Reproduce:
1. Configure two volumes on two different servers in replication
mode(configuration in attachment).
2. Modify content of the files periodically (for instance once per minute).
3. Observe that memory of the glusterfsd permanently increasing.

Actual results:
Memory consumption of the glusterfsd process growth and never releases.

Expected results:
Memory consumption of the glusterfsd should not permanently growth while the
size of the mounted directory is not increasing.
