hi Philip,
    When this happens could you post the statedump of the process to see what is causing this memory usage. 
Steps to grab statedump of the process:
1) kill -USR1 <pid-of-nfs-process>
2) the file is located at /tmp/glusterdump.<pid-of-nfs-process>

Subject: [Gluster-users] Memory leak with glusterfs NFS on 3.2.6


we're running a distributed-replicated setup for our images, and while
we use a caching proxy for the hotset, quite a few requests land on
glusterfs (3.2.6 on squeeze). Since glusterfs fuse client experiences
regular hangs which require reboots (I couldnt yet find a solution to
that), we run on NFS.

NFS however, specifically the glusterfs process, eats memory like
crazy, around 3-4GB a week, until we (have to) restart it.

Does/did anybody experience this problem, and if so, did you find a
way to mitigate it?
