<div dir="ltr"><div><div>hi Zdenek,<br></div> I recently found this issue and there has been a discussion on gluster-devel about how to fix this. It is a bit involved, so taking more time than I would like to fix, this bug has been there for almost 3-4 years I guess.<br><br></div>You can find the discussion here: <a href="http://www.gluster.org/pipermail/gluster-devel/2016-July/050085.html">http://www.gluster.org/pipermail/gluster-devel/2016-July/050085.html</a><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Aug 19, 2016 at 7:10 PM, Zdenek Styblik <span dir="ltr"><<a href="mailto:zdenek.styblik@showmax.com" target="_blank">zdenek.styblik@showmax.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello,<br>
<br>
we've found a memory leak in glusterd v3.7.x(currently at v3.7.14, but<br>
we are users of v3.7.x from the beginning).<br>
It seems, we've empirically verified, that continuous execution of %<br>
gluster volume set <volname> <key> <value>; leads to memory leaks in<br>
glusterd and OOM, although not necessarily OOM of glusterd itself.<br>
Settings which were being set over and over again are<br>
`nfs.addr-namelookup false` and `nfs.disable true`. There might have<br>
been other settings, but I was able to find these in recent logs.<br>
Unfortunately, we don't have capacity to debug this issue<br>
further(statedumps are quite overwhelming :] ).<br>
Repeated execution has been caused due to bug in Puppet module we're<br>
using(and we were able to address this issue). Therefore, it's safe to<br>
say that the number of affected users or like hood of somebody else<br>
having these problem is probably low. It's still a memory leak and,<br>
well, rather serious one if you happen to stumble upon it. Also, it<br>
must be noted that this gets amplified if you have more than just<br>
volume.<br>
<br>
If there is anything I can help with, let me know.<br>
