            <title>[SERVER-1704] mongod crashes, may be related to out of disk space</title>
                <link>https://jira.mongodb.org/browse/SERVER-1704</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Problem:&lt;br/&gt;
I was testing a data load script. During the testing I ran out of disk space. &lt;/p&gt;

&lt;p&gt;From the mongo client, I could still query and get results&lt;/p&gt;

&lt;p&gt;&amp;gt; db.blogs.count()&lt;br/&gt;
57389495&lt;br/&gt;
&amp;gt; db.blogs.find()&lt;/p&gt;
{ &quot;_id&quot; : ObjectId(&quot;4c7c20be8da65f35566b911f&quot;), &quot;author&quot; : &quot;jim&quot;, &quot;ts&quot; : &quot;Mon Aug 30 2010 14:21:02 GMT-0700 (PDT)&quot;, &quot;tags&quot; : [ &quot;yes&quot;, &quot;no&quot; ] }
{ &quot;_id&quot; : ObjectId(&quot;4c7c20be8da65f35566b9120&quot;), &quot;author&quot; : &quot;jim&quot;, &quot;ts&quot; : &quot;Mon Aug 30 2010 14:21:02 GMT-0700 (PDT)&quot;, &quot;tags&quot; : [ &quot;yes&quot;, &quot;no&quot; ] }
{ &quot;_id&quot; : ObjectId(&quot;4c7c20be8da65f35566b9121&quot;), &quot;author&quot; : &quot;jim&quot;, &quot;ts&quot; : &quot;Mon Aug 30 2010 14:21:02 GMT-0700 (PDT)&quot;, &quot;tags&quot; : [ &quot;yes&quot;, &quot;no&quot; ] }

&lt;p&gt;However, after I performed a collection.drop() it appeared that the mongod process died&lt;/p&gt;

&lt;p&gt;&amp;gt; db.blogs.drop()&lt;br/&gt;
true&lt;br/&gt;
&amp;gt; use scaleout&lt;br/&gt;
switched to db scaleout&lt;br/&gt;
&amp;gt; for (i=0; i &amp;lt; 10; i++) { db.blogs.insert(&lt;/p&gt;
{ author: &apos;jim&apos;, ts : new Date(), tags : [&quot;yes&quot;,&quot;no&quot;] }
&lt;p&gt;); } &lt;br/&gt;
dbconnectionpool: connect failed 10.242.221.155:27000 : couldn&apos;t connect to server 10.242.221.155:27000}&lt;/p&gt;

&lt;p&gt;Looking at the log file I see the following assert&lt;/p&gt;

&lt;p&gt;Tue Aug 31 00:04:18 &lt;span class=&quot;error&quot;&gt;&amp;#91;conn15&amp;#93;&lt;/span&gt;  Caught Assertion in insert , continuing&lt;br/&gt;

&lt;p&gt;Reproduce:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;create a DB with limited free space (say 1GB)&lt;/li&gt;
	&lt;li&gt;insert into the DB and fill up the available disk space&lt;/li&gt;
	&lt;li&gt;once the DB is out of space, do a db.collection.drop()&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Workaround:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;allocate more disk space&lt;/li&gt;
	&lt;li&gt;restart the db with the &quot;--repair&quot; flag&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Business Case:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;Reliability&lt;/li&gt;
	&lt;li&gt;User Expereince&lt;/li&gt;

&lt;p&gt;From the log snippet it looks like several things are happening at once here - inserts, drops, shutdowns.  Would be helpful if you could provide the full log.  Is it still available?&lt;/p&gt;</comment>
