Valgrind log obtained by running dbench for just 864 seconds(1/100th) of a day
Description of problem:
Several GlusterFS users report ravenous memory consumption by Gluster Nfs in 3.2.x versions over days of operation under heavy load, (possibly) causing performance degradation.
Version-Release number of selected component (if applicable):
3.2.x, possible 3.3.x and mainline
How reproducible: always
Steps to Reproduce:
1. run dbench/<insert heavy load ops here> on an nfs mount
GNFS leaks a lot a memory and this could be the reason for performance degradation (not 100% sure).
Attached valgrind log.
