            <title>[SERVER-22618] RangeDeleter asserts and causes primary to be unusable</title>
                <link>https://jira.mongodb.org/browse/SERVER-22618</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;#8.&lt;/p&gt;

&lt;p&gt;Note: this looks like &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-22390&quot; title=&quot;RangeDeleter crashes primary node due to lagging secondary&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-22390&quot;&gt;&lt;del&gt;SERVER-22390&lt;/del&gt;&lt;/a&gt; but is totally different - please read carefully.&lt;/p&gt;

&lt;p&gt;Our setup: primary+secondary+arbiter+another secondary which is &amp;gt;1 hour behind and syncing. in SECONDARY. we added it as votes:0 and priority:0 so it will not crash (as a workaround &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-22390&quot; title=&quot;RangeDeleter crashes primary node due to lagging secondary&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-22390&quot;&gt;&lt;del&gt;SERVER-22390&lt;/del&gt;&lt;/a&gt;)&lt;/p&gt;

&lt;p&gt;The other secondary is perfectly sync&apos;d (0 sec lag).&lt;/p&gt;

&lt;p&gt;Range deleter shows this:&lt;/p&gt;

&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;Note: this DOES NOT crash the node, it keeps living - but - after exactly 1 hour, the primary becomes unusable and very very slow.&lt;/p&gt;

&lt;p&gt;1. This is a bug.&lt;/p&gt;

&lt;p&gt;2. Why does the range deleter wait for the secondary if it has votes:0 and priority:0?&lt;/p&gt;

&lt;p&gt;3. Any workaround for this? This will happen again.&lt;/p&gt;</description>

&lt;p&gt;As Andy mentioned in the comment above, the assertion and stack trace are not the interesting issue here.  But it does indicate that the &lt;tt&gt;w:2&lt;/tt&gt; write during the range deletion timed out.  Which likely means you have replication lag in your system, and this log message is a symptom of a different problem, not the problem in itself.&lt;/p&gt;

&lt;p&gt;Thanks&lt;br/&gt;
Dan&lt;/p&gt;</comment>

                            <comment id="1230732" author="schwerin" created="Fri, 8 Apr 2016 20:25:50 +0000"  >&lt;p&gt;I&apos;ve done a bit of digging, and the stack trace is almost certainly not the cause of the primary becoming very very slow. In fact, there&apos;s really no reason to print the stack trace. It&apos;s acceptable for secondary throttle waits to time out, and while they cancel the current range deletion task, they do not by themselves destabilize or endanger the system.&lt;/p&gt;

&lt;p&gt;The two interesting questions are &lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;why did waiting for w:2 replication during the range delete time out in this case, and&lt;/li&gt;
	&lt;li&gt;Was that timeout causally related to the later performance problem.&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;The data available in the ticket are insufficient to answer either question, and we have not been able to reproduce the performance behavior in house.&lt;/p&gt;</comment>

&lt;p&gt;This happened in our production servers and due to this bug (and others) - we are preventing lagging secondaries. We cannot dedicate the efforts to try to reproduce this on our test environment.&lt;/p&gt;

&lt;p&gt;I wouldn&apos;t close this issue if I were you. This is an assert, which needs to be rethinked, even if not reproduced. The description above should be enough to show the potential of what it does.&lt;/p&gt;</comment>
                            <comment id="1205815" author="misha.tyulenev" created="Wed, 16 Mar 2016 19:26:18 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=yoni%40appsee.com&quot; class=&quot;user-hover&quot; rel=&quot;yoni@appsee.com&quot;&gt;yoni@appsee.com&lt;/a&gt; , could you please clarify if the issue is still happening and if so could you please provide more info to help reproducing the problem?&lt;br/&gt;
Thanks!&lt;/p&gt;</comment>
                            <comment id="1179396" author="misha.tyulenev" created="Fri, 19 Feb 2016 21:16:01 +0000"  >&lt;p&gt;Thanks for submitting the issue description.&lt;br/&gt;
Currently I can not reproduce the issue, here is the shard&apos;s replica set config used:&lt;br/&gt;
Primary (P), &lt;br/&gt;
Secondary1: no lag (S1), &lt;br/&gt;
Secondary 2: &amp;gt; 1hr lag, votes:0, priority:0 (S2) , &lt;br/&gt;
Arbiter (A)&lt;/p&gt;

&lt;p&gt;To the point 2 in the report:  votes:0, priority:0  should not affect the replication sync behavior, because in this case moveChunk which is issued by balancer in migration thread should use writeConcern w:2 that will be satisfied if P and S1 are healthy. To confirm and identify the issue we need more info:&lt;/p&gt;

&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;Could you please add a rs.status() for the shard that has an issue?&lt;/li&gt;
	&lt;li&gt;Could you please send logs around time when the primary becomes  &quot;very very slow&quot; ?&lt;/li&gt;
	&lt;li&gt;Could you please send db.settings.find() output from admin db, I want to be sure that the balancer does not have w:3 writeConcern settings that will trigger the issue reported.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Thanks!&lt;/p&gt;</comment>
