            <title>[JAVA-1036] getCollectionNames() causing a &quot;ids don&apos;t match&quot; exception intermittently</title>
                <link>https://jira.mongodb.org/browse/JAVA-1036</link>
                <project id="10006" key="JAVA">Java Driver</project>
                    <description>&lt;p&gt;I&apos;m running into an intermittent error when running a bunch of unit tests (though it also occurs when I run a specific test). Before running the tests I clear the mongo database table by table. Every now and then I get the following:&lt;/p&gt;

&lt;p&gt;Oct 31, 2013 1:22:27 PM com.mongodb.DBPortPool gotError&lt;br/&gt;
WARNING: emptying DBPortPool to /127.0.0.1:27017 b/c of error&lt;br/&gt;
com.mongodb.MongoException: ids don&apos;t match&lt;br/&gt;
	at com.mongodb.DBTCPConnector.innerCall(DBTCPConnector.java:285)&lt;br/&gt;
	at com.mongodb.DBTCPConnector.call(DBTCPConnector.java:256)&lt;br/&gt;

	at com.mongodb.DBApiLayer$MyCollection.__find(DBApiLayer.java:274)&lt;br/&gt;
	at com.mongodb.DB.getCollectionNames(DB.java:381)&lt;br/&gt;
	at com.parc.cip.repository.MongoDatabaseBridge.cleanDB(MongoDatabaseBridge.java:74)&lt;/p&gt;

&lt;p&gt;the line in file is:&lt;/p&gt;

&lt;p&gt;Set&amp;lt;String&amp;gt; collectionNames = db.getCollectionNames();&lt;/p&gt;

&lt;p&gt;This has been replicated on a few different machines. I am running 2.4.7 of the mongo database.&lt;/p&gt;</description>

&lt;p&gt;I haven&apos;t heard back from you in a while, so I&apos;m going to close this.  Please feel free to re-open if you have more information.&lt;/p&gt;

&lt;p&gt;I need some more information, as I don&apos;t have enough yet to attempt to reproduce this and the root cause is not obvious:&lt;/p&gt;

&lt;ol&gt;
	&lt;li&gt;How do you create your Mongo instance (i.e., which constructor do you use and what arguments do you pass)?&lt;/li&gt;
	&lt;li&gt;Are your tests multi-threaded?&lt;/li&gt;
	&lt;li&gt;Are there any other errors in the client or the server logs?&lt;/li&gt;
	&lt;li&gt;When you run the specific test, does it occur consistently or still intermittently?&lt;/li&gt;
&lt;/ol&gt;
