            <title>[SERVER-44945] aggregate failed at assertion src\\mongo\\db\\pipeline\\value.cpp:1365</title>
                <link>https://jira.mongodb.org/browse/SERVER-44945</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;h1&gt;&lt;a name=&quot;myquery%3A&quot;&gt;&lt;/a&gt;&lt;b&gt;my query:&lt;/b&gt;&lt;/h1&gt;
&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;db.transactions.aggregate([{$group:{_id:{hash:&quot;$hash&quot;},count:{$sum:1}}},{$match:{count:{$gt:1}}}],{allowDiskUse:true})&lt;/span&gt;&lt;/pre&gt;

&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;
&lt;p&gt;I use this query to find duplicates of hash field, but every time I get&#160; below error msg when I execute this query. this transaction collection contain 0.5 billion documents, so it takes a while to aggregate, which it&apos;s totally understandable, but getting error msg is something I didn&apos;t understand. because I execute the same query at another smaller transaction collection in another database where it contain just maybe tens of thousands of documents, and it worked. but for 0.5 billion documents collection, it doesn&apos;t work.&#160;&lt;/p&gt;
&lt;h1&gt;&lt;a name=&quot;errormsg%3A&quot;&gt;&lt;/a&gt;&lt;b&gt;error msg:&lt;/b&gt;&lt;/h1&gt;

                            <comment id="2593841" author="carl.champain" created="Mon, 9 Dec 2019 15:45:37 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=liqy0906%40gmail.com&quot; class=&quot;user-hover&quot; rel=&quot;liqy0906@gmail.com&quot;&gt;liqy0906@gmail.com&lt;/a&gt;,&lt;/p&gt;

&lt;p&gt;After further investigation, we think that this ticket is a duplicate of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-43151&quot; title=&quot;Error in aggregation assertion at value.cpp:1368&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-43151&quot;&gt;&lt;del&gt;SERVER-43151&lt;/del&gt;&lt;/a&gt;, which is now closed and has a fix for several versions. I recommend you upgrading to the appropriate one:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;Fix in already available releases 4.3.1 and 4.2.2&lt;/li&gt;
	&lt;li&gt;Fix in upcoming releases 3.6.17, 3.4.24 and 4.0.14&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;I&apos;m going to close this ticket, but if after upgrading you continue to experience this issue, please provide the requested information above, and I will reopen the ticket.&lt;/p&gt;

&lt;p&gt;Thank you,&lt;br/&gt;

&lt;p&gt;Thanks for the report.&lt;br/&gt;
 To help us understand what is happening, can you please provide:&lt;/p&gt;

	&lt;li&gt;The collection stats: &lt;tt&gt;db.transactions.stats()&lt;/tt&gt; ?&lt;/li&gt;
	&lt;li&gt;The index information: &lt;tt&gt;db.transactions.getIndexes()&lt;/tt&gt; ?&lt;/li&gt;
	&lt;li&gt;The &lt;tt&gt;explain()&lt;/tt&gt; output for this query: &lt;tt&gt;db.transactions.explain().aggregate(&lt;span class=&quot;error&quot;&gt;&amp;#91;...&amp;#93;&lt;/span&gt;)&lt;/tt&gt;?&#160;&lt;/li&gt;
	&lt;li&gt;The &lt;tt&gt;mongod.log&lt;/tt&gt; file for this node?&lt;/li&gt;
