            <title>[SERVER-19917] MongoDB crashed while loading bulk data</title>
                <link>https://jira.mongodb.org/browse/SERVER-19917</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;MongoDB getting crashed frequently ( once in an hour) .  I am running Single node Mongo DB 3.0.4 with Wired tiger on 3.14.26-24.46.amzn1.x86_64. &lt;/p&gt;

&lt;p&gt;The log says out of memory . But the instance has 50 % disk space. &lt;/p&gt;

&lt;p/&gt;

                            <comment id="1014450" author="ramon.fernandez" created="Tue, 25 Aug 2015 22:28:41 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=vengireturns%40gmail.com&quot; class=&quot;user-hover&quot; rel=&quot;vengireturns@gmail.com&quot;&gt;vengireturns@gmail.com&lt;/a&gt;, this machine is seriously underpowered to run MongoDB. For starters, the default WiredTiger cache size is 1GB, so it&apos;s not surprising &lt;tt&gt;mongod&lt;/tt&gt; run quickly out of memory.&lt;/p&gt;

&lt;p&gt;You may be able to get things to work by lowering the WiredTiger cache considerably; for example, here&apos;s the command line argument to set it to 100M:&lt;/p&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;--wiredTigerEngineConfigString=&quot;cache_size=100M&quot;&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;Needless to say there&apos;s a performance tradeoff, so you may want to consider a machine with a lot more memory.&lt;/p&gt;

&lt;p&gt;I&apos;m closing this ticket as I don&apos;t see an evidence of a bug, and we keep the SERVER project for reporting bugs or feature suggestions for the MongoDB server. For MongoDB-related support discussion please post on the &lt;a href=&quot;http://groups.google.com/group/mongodb-user&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mongodb-user group&lt;/a&gt; or &lt;a href=&quot;http://stackoverflow.com/questions/tagged/mongodb&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Stack Overflow with the &lt;tt&gt;mongodb&lt;/tt&gt; tag&lt;/a&gt;, where your question will reach a larger audience.

The instance has 1 GB memory and 30GB disk space . But no swap memory was configured.. And there is no cgroup has been configured.&lt;/p&gt;

&lt;p&gt;Our development team is loading the data from Spring data repository using a java program (12 million documents in chunks of 10000 each). So i couldn&apos;t share the data to you.&lt;/p&gt;

&lt;p&gt;plz let me know if you need any details.&lt;/p&gt;</comment>

The &lt;tt&gt;mongostat&lt;/tt&gt; output you sent shows an increase in memory usage, but should not be enough to trigger this issue. Can you please tell us:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;how much memory you have in this machine&lt;/li&gt;
	&lt;li&gt;the output of &quot;ulimit -a&quot;&lt;/li&gt;
	&lt;li&gt;whether you have cgroups configured&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Also, what kind of bulk loading are you doing and how? Which driver are you using? I&apos;m asking because if you provide enough details, even share the data you&apos;re uploading&lt;span class=&quot;error&quot;&gt;&amp;#91;1&amp;#93;&lt;/span&gt;, we can try to reproduce locally.&lt;/p&gt;

&lt;p&gt;Thanks,&lt;br/&gt;
Ram&#243;n.&lt;/p&gt;

&lt;p&gt;&lt;span class=&quot;error&quot;&gt;&amp;#91;1&amp;#93;&lt;/span&gt; If you can upload your data let me know and I&apos;ll create an upload portal for you; JIRA only supports 150MB uploads.&lt;/p&gt;</comment>

&lt;p&gt;Thanks for your quick response. I did tested the load again in 3.0.5. It performed well this  time. However at the end of the load , it failed again  with memory issue. below the error for your reference.&lt;/p&gt;

                            <comment id="1004631" author="ramon.fernandez" created="Thu, 13 Aug 2015 17:31:58 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=vengireturns%40gmail.com&quot; class=&quot;user-hover&quot; rel=&quot;vengireturns@gmail.com&quot;&gt;vengireturns@gmail.com&lt;/a&gt;, I wanted to add a bit more information to this ticket.&lt;/p&gt;

&lt;p&gt;The stack trace indicates that an attempt to allocate memory failed, which caused &lt;tt&gt;mongod&lt;/tt&gt; to terminate (this is by design). In 3.0.4 there were a number of cases where WiredTiger would consume large amounts of memory, which we can trigger behaviors like the one you described in this ticket. MongoDB 3.0.5 shipped with fixes for this cases, but also included a performance enhancement that may also cause increased memory consumption. The relevant tickets are:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-19673&quot; title=&quot;Excessive memory allocated by WiredTiger journal&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-19673&quot;&gt;&lt;del&gt;SERVER-19673&lt;/del&gt;&lt;/a&gt; (fixed in 3.0.6)&lt;/li&gt;
	&lt;li&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-17386&quot; title=&quot;Cursor cache causes excessive memory utilization in WiredTiger&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-17386&quot;&gt;&lt;del&gt;SERVER-17386&lt;/del&gt;&lt;/a&gt; (fixed in 3.0.5)&lt;/li&gt;
	&lt;li&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-18829&quot; title=&quot;Cache usage exceeds configured maximum during index builds under WiredTiger&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-18829&quot;&gt;&lt;del&gt;SERVER-18829&lt;/del&gt;&lt;/a&gt; (fixed in 3.0.5)&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;MongoDB 3.0.6-rc0 release candidate includes fixes for all three tickets, and we believe it should address the out-of-memory condition you&apos;re seeing &amp;#8211; hence the suggestion to try it out. If you&apos;re open to sharing the data you&apos;re bulk-uploading with us we can run the experiments on our end &amp;#8211; you can &lt;a href=&quot;https://10gen-httpsupload.s3.amazonaws.com/upload_forms/41b4a65c-7602-464c-abb2-6eb6f114f466.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;upload data privately and securely here&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;If the out-of-memory condition reproduces with 3.0.6-rc0 then we may be looking at a new problem, and we&apos;ll ask you to collect some data to investigate further. &lt;/p&gt;

&lt;p&gt;Thanks,&lt;br/&gt;
Ram&#243;n.&lt;/p&gt;
