Bug 1291479

Created attachment 1105748 [details]
Statedumps for both server and client

Description of problem: Fuse client appears to be building a large number of threads and the shared pool of ram? appears to be consuming more than is allocated and is failing to release memory. This server's uptime has only been 19 days so the amount of memory leakage appears somewhat substantial.

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

sudo dpkg -l | grep gluster
ii  glusterfs-client                 3.7.6-ubuntu1~trusty1               amd64        clustered file-system (client package)
ii  glusterfs-common                 3.7.6-ubuntu1~trusty1               amd64        GlusterFS common libraries and translator modules



How reproducible: Unsure


Steps to Reproduce:
1. Create a 500GB 3-way replicated with quorum 2 (fixed) enabled.
2. Load it up with lots of small files (1kb - 50 kb) to about 55% full (not all files are this small, but the primary file type are PHP scripts).
3. Run it for an extended period of time doing the typical actions -- replace entire directories, symlink, rsync periodically for backups (READ FROM Gluster).

Actual results:
Memory leaking?

Memory consumption is very high to the point of swapping. Rebooting the client clears the issue.

Expected results:
Not memory leaking?
