CHANGE: http://review.gluster.com/3641 (nfs: memory leak fixes) merged in release-3.2 by Anand Avati (avati) |
Created attachment 594166 [details] 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 Actual results: GNFS leaks a lot a memory and this could be the reason for performance degradation (not 100% sure). Additional info: Attached valgrind log.
