Hi, I upgraded our lustre server version from 2.1.6 to the b2_5 tip, server side seems to work ok after writeconf/erase-param/quota stuff. But el6.5 client leaks memory very rapidly, usually after couple of hours nagios checks starts to hang (ps). I've attached leak_finder.pl logs here: http://www.puuppa.org/~teve/lustre_251_leak.log.bz2 Regards, Tommi
