                            <comment id="336905" author="thomasr" created="Thu, 16 May 2013 07:09:33 +0000"  >&lt;p&gt;This says that the BSON document didn&apos;t pass the validation, because the size was larger than 16MB. This doesn&apos;t mean that the size of the BSON document actually was larger, it can also happen if the BSON document got corrupted and the field that stores the size at the beginning of a BSON document has changed to a larger number.&lt;/p&gt;

&lt;p&gt;You can also see some other errors in your logfile, for example&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;Wed May 8 10:37:30 [conn979] Assertion: 13655:BSONElement: bad type 115&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;Type 115 doesn&apos;t exist, so this really looks like your data got corrupted and the BSON representation didn&apos;t make sense anymore. The corruption can occur through disk or network related problems for example.&lt;/p&gt;

&lt;p&gt;Does that answer your question?&lt;/p&gt;

&lt;p&gt;Regards,&lt;br/&gt;

&lt;p&gt;I have a question about the contents of the above,what it tells us?&lt;br/&gt;
what&apos;s kind of the error?&lt;/p&gt;

&lt;p&gt;Regards. &lt;/p&gt;</comment>
                            <comment id="335946" author="thomasr" created="Wed, 15 May 2013 05:52:33 +0000"  >&lt;p&gt;I&apos;m glad the index build worked for you in the end. I am not sure why it didn&apos;t work with &quot;dropDups&quot;, this may be an exception for the _id index. Like I said, it&apos;s not normal procedure to drop the _id index, so you should never have to create one manually. &lt;/p&gt;

&lt;p&gt;My guess is that the problem was a corruption in your data (see the assertions in your logfile) and somehow there were duplicate _id entries, which should never happen. That&apos;s what made the index build fail and hence you didn&apos;t have an _id index anymore. &lt;/p&gt;

&lt;p&gt;As such, since we can&apos;t reproduce this problem, I would suggest to close this ticket now. You can re-open it at any time if this problem occurs again. Or is there anything else you&apos;d like me to do on the ticket?&lt;/p&gt;

&lt;p&gt;Regards,&lt;br/&gt;

It&apos;s puzzle.&lt;br/&gt;
That&apos;s normal when executing commands with &apos;dropDups&apos; on key except for &apos;_id&apos;.&lt;/p&gt;

I could remove duplicates manually,and then it&apos;s successful that building the &apos;_id&apos; index.&lt;/p&gt;

&lt;p&gt;I&apos;m not aware of any way to drop the _id index, it is not supported in MongoDB. Since you have several documents with the same _id in your collection, can you remove duplicates manually and then try building the index again?&lt;/p&gt;

&lt;p&gt;Thomas&lt;/p&gt;</comment>
                            <comment id="332612" author="handy" created="Fri, 10 May 2013 07:24:03 +0000"  >&lt;p&gt;hi,&lt;br/&gt;
could you give me some suggests or answers to solve the problem,&lt;br/&gt;
thank you!&lt;/p&gt;</comment>

&lt;p&gt;it didn&apos;t work when i rebuilt/built the _id index with dropdups ,why?&lt;/p&gt;

&lt;p&gt;can i drop the _id index for simulating the Situation by some way&#65311;&lt;/p&gt;</comment>
                            <comment id="330827" author="handy" created="Wed, 8 May 2013 06:04:18 +0000"  >&lt;p&gt;Hi,&lt;/p&gt;

&lt;p&gt;The logfile errors refer to a collection VTR in the database RDB. In your screenshots, the database was &quot;RELATIONDB&quot; and the collection was &quot;REALTOVIRTUAL&quot;. Are these two different databases/collections?&lt;br/&gt;
RELATIONDB is the same as RDB,i just rename RELATIONDB to RDB in the log&lt;br/&gt;
this error has appeared many times in different instances&lt;br/&gt;
it doesn&apos;t matter the different from the names&lt;/p&gt;

&lt;p&gt;Can you run a find with the offending _id and see if it returns more than one document?&lt;br/&gt;
i had excuted db.VIRTUALTOREAL.find({_id:&quot;1903935564_14401&quot;}) before, it returned two document&lt;/p&gt;

&lt;p&gt;Can you also tell me the current state? Were you able to rebuilt the _id index in the mean time or is it still missing?&lt;br/&gt;
you can see it in 1.jpg of Attachments, 2.jpg can show you it didn&apos;t work&lt;/p&gt;

&lt;p&gt;by the way, i run &quot;repair&quot; ,then solve it&lt;/p&gt;</comment>
                            <comment id="330812" author="thomasr" created="Wed, 8 May 2013 05:25:11 +0000"  >&lt;p&gt;Hi, &lt;/p&gt;

&lt;p&gt;when a &lt;tt&gt;compact&lt;/tt&gt; starts, it first drops all the indexes (including _id). This is normal behavior. They are normally rebuilt at the end of the &lt;tt&gt;compact&lt;/tt&gt;.&lt;/p&gt;

&lt;p&gt;In your case, it seems the &lt;tt&gt;compact&lt;/tt&gt; did not finish but stopped with an error:&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;/td&gt;
		&lt;/tr&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-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;Wed May 8 10:40:45 [conn979] command RDB.$cmd command: { compact: &quot;VTR&quot; } ntoreturn:1 exception: E11000 duplicate key error index: RDB.VTR.$id dup key: { : &quot;1903935564_14401&quot; } code:11000 reslen:228 1605378ms&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;The logfile errors refer to a collection &lt;tt&gt;VTR&lt;/tt&gt; in the database &lt;tt&gt;RDB&lt;/tt&gt;. In your screenshots, the database was &quot;RELATIONDB&quot; and the collection was &quot;REALTOVIRTUAL&quot;. Are these two different databases/collections? &lt;/p&gt;

&lt;p&gt;The missing _id index can be explained by the failure of the compact command. It doesn&apos;t explain though how you could have a duplicate key violation on the &lt;tt&gt;_id&lt;/tt&gt; index. This may be related to the termination (&lt;tt&gt;kill -9&lt;/tt&gt;) of your mongod and deletion of the journal file afterwards.&lt;/p&gt;

&lt;p&gt;Can you run a find with the offending _id and see if it returns more than one document?&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;/td&gt;
		&lt;/tr&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-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.VTR.find({_id: &quot;1903935564_14401&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;Can you also tell me the current state? Were you able to rebuilt the _id index in the mean time or is it still missing?&lt;/p&gt;

&lt;p&gt;    the collection is not a capped collection, i use version 2.2.0&lt;/p&gt;

&lt;p&gt;    first my mongo is killed(-9) by someone, i use journal default,&lt;br/&gt;
    but i found some errors during journal in the log, then i remove the journal.&lt;br/&gt;
    it seems like normal at the begging, it is unnormal after running some days, the query or the update is slowly(about cost 20s or 30s).&lt;br/&gt;
    so i try to excute &quot;compact&quot;.&lt;br/&gt;
     &quot;assertion&quot; : &quot;E11000 duplicate key error index&quot; appears in the end&lt;/p&gt;

&lt;p&gt;Is the collection a capped collection? Prior to version 2.2, capped collections did not have an index on &lt;tt&gt;_id&lt;/tt&gt;. &lt;/p&gt;

&lt;p&gt;If this is not a capped collection and if it had an index on &lt;tt&gt;_id&lt;/tt&gt; before, can you explain step by step what you did? &lt;/p&gt;

&lt;p&gt;Has the compact been interrupted in any way?&lt;/p&gt;

&lt;p&gt;Also, did you up- or downgrade mongodb at any time recently?&lt;/p&gt;

&lt;p&gt;Can you also please attach the logfile from a point before starting the compact command to a point after the compact has finished? If the logfile contains sensitive information, please let me know and I can provide a way to upload the logfile securely to our server.&lt;/p&gt;

&lt;p&gt;Regards,&lt;br/&gt;
Thomas&lt;/p&gt;</comment>
