            <title>[SERVER-24776] Unable to recover after fassert(): too many open files</title>
                <link>https://jira.mongodb.org/browse/SERVER-24776</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Hey guys,&lt;/p&gt;

&lt;p&gt;My databases and all collections just disappeared after a crash.&lt;br/&gt;
It looks something like &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-19774&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://jira.mongodb.org/browse/SERVER-19774&lt;/a&gt;.&lt;br/&gt;
It started off with the crash (could restart daemon but without databases and collections) and now I can no longer start the daemon. (I have about a week to finish running experiments for my thesis so any help on recover is much appreciated).&lt;/p&gt;

&lt;p&gt;I&apos;ve described the issue here: &lt;a href=&quot;http://stackoverflow.com/questions/38004375/mongodb-databases-disappeared?noredirect=1#comment63461612_38004375&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://stackoverflow.com/questions/38004375/mongodb-databases-disappeared?noredirect=1#comment63461612_38004375&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Please let me know whatever you need and I&apos;ll make sure you get it.&lt;/p&gt;

&lt;p&gt;It should be noted last I checked one database was 5GB and the other was &amp;lt; 500 MB.&lt;/p&gt;</description>

Another thing is that moving the journaling allowed me tor restart it. Here&apos;s the error:&lt;/p&gt;

&lt;p&gt;What fixed that was to move the journals out of the database path which allows me to restart the daemon. Moving it back and restarting the daemon allows me to start it, but it still does not produce any of the records I had previously put into it. Primarily saying this for completeness. I&apos;ll post it to the mailing list once I have time.&lt;/p&gt;

&lt;p&gt;I&apos;ll try updating to latest patch, but not hoping for much there.&lt;/p&gt;</comment>

I I&apos;ll post it to the user group as well but (since my experiments for my thesis are to be done in a couple of days I&apos;ll ask here too) I tried to increase the max number of files which was the change that made me unable to start the daemon as well. &lt;br/&gt;
Do you have an idea as to why that is? I can&apos;t see anything in the logs for that. &lt;/p&gt;</comment>

&lt;p&gt;Also I see you&apos;re using 3.2.0 &amp;#8211; I&apos;d recommend you always use the latest patch release in a given version (3.2.7 at the moment).&lt;/p&gt;

&lt;p&gt;Please note that the SERVER project is for reporting bugs or feature suggestions for the MongoDB server.

A question like this involving more discussion would be best posted 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;.
