                <link>https://jira.mongodb.org/browse/SERVER-27064</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;see these errors when running mongo and mongorestore:&lt;br/&gt;
mongo(821,0x7fffbc3713c0) malloc: *** malloc_zone_unregister() failed for 0x7fffbc367000&lt;br/&gt;
mongorestore(1055,0x7fffbc3713c0) malloc: *** malloc_zone_unregister() failed for 0x7fffbc367000&lt;/p&gt;

&lt;p&gt;It may be related to the recent upgrade to Sierra.&lt;/p&gt;

Can you please attempt to reproduce with the latest Sierra updates installed and the latest mongodb homebrew packages? Without a local reproduction I cannot easily verify that the proposed workaround actually fixes anything.&lt;/p&gt;

&lt;p&gt;Also, could you please clarify - when you observed these messages, was this a hard stop of the tool or component, or just something logged to the console during startup? If the latter, I&apos;m less inclined to risk a backport to a stable release.&lt;/p&gt;</comment>

&lt;p&gt;Thanks&lt;/p&gt;

                            <comment id="1464101" author="acm" created="Thu, 22 Dec 2016 16:22:05 +0000"  >&lt;p&gt;Hi &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=justronin&quot; class=&quot;user-hover&quot; rel=&quot;justronin&quot;&gt;justronin&lt;/a&gt; - &lt;/p&gt;

&lt;p&gt;Please note that MongoDB 2.6 is end-of-life, and also that at least for me, the mongodb26 homebrew package no longer exists. However, we suspect that this issue exists in later versions of MongoDB as well (well, technically the issue would exist within our built-in copy of gperftools).&lt;/p&gt;

&lt;p&gt;Could you please try installing each of the following homebrew mongodb packages on your Seirra machine (unfortunately, I don&apos;t currently have access to one or I would do this myself) and see if you still observe this error:&lt;/p&gt;

&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;mongodb30&lt;/li&gt;
	&lt;li&gt;mongodb32&lt;/li&gt;
	&lt;li&gt;mongodb&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;The last one is the newly released 3.4. It may be that this issue was resolved already, since we have upgraded the gperftools version across these stable releases. MongoDB 2.6 used gperftools-2.0, MongoDB 3.0 and 3.2 used gperftools-2.2, and MongoDB 3.4 uses gperftools-2.5.&lt;/p&gt;

&lt;p&gt;That data would be very valuable to us as it would let us understand which supported stable releases are affected, and help us plan how to manage backporting any fix.&lt;/p&gt;</comment>
