Fixed In Version: glusterfs-3.8.4-1
Doc Type: Bug Fix
Doc Text:
After a connection failure, the Gluster FUSE client did not correctly clean up threads spawned to handle the failure, which resulted in a memory leak. This caused a crash when the process was killed to reclaim memory. Threads are now cleaned up correctly and the process is no longer killed, preventing the crash.

Upstream patch available at:
http://review.gluster.org/#/c/14661/
Comment 8 Atin Mukherjee 2016-09-17 11:59:57 UTC 
Upstream mainline : http://review.gluster.org/14875
Upstream 3.8 : http://review.gluster.org/14979

And the fix is available in rhgs-3.2.0 as part of rebase to GlusterFS 3.8.4.
Comment 12 Prasad Desala 2016-10-25 09:13:05 UTC 
Followed the same steps updated in Comment 11 on a 3.1.3 system. I am able to see continuous "DNS resolution failed" errors in the fuse logs and the memory usage keeps growing which results the system to crash.
 
Same steps were followed to verify this BZ on a 3.8.4-2.el7rhgs.x86_64 system. After the fix, no memory leak is seen due to the "DNS resolution failed" errors.

Hence, moving this BZ to Verified.
