            <title>[SERVER-21619] sys-perf: WT crash during core_workloads_WT execution </title>
                <link>https://jira.mongodb.org/browse/SERVER-21619</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;There were some random crashes of mongod during core_workloads_WT test in system-perf. observations:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;this happens in all non-sharded setups (standalone, 1-node replSet, 3-node replSet) randomly&lt;/li&gt;
	&lt;li&gt;Seems that it always happens during insert_ttl test&lt;/li&gt;
	&lt;li&gt;There was no core file generated, I am trying to figure out why. I did apply &quot;ulimit -c unlimited&quot; during start up mongod.&lt;/li&gt;
	&lt;li&gt;Manual run of insert_ttl does not re-create the crash yet, maybe need to run the whole suite?&lt;/li&gt;
	&lt;li&gt;The earliest SHA with this issue is 3f598f1edc (&lt;a href=&quot;https://evergreen.mongodb.com/task/sys_perf_linux_3_node_replSet_core_workloads_WT_3f598f1edc57ca0b863b58009e7cca9a986d4da7_15_11_19_14_56_32/0&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;test report&lt;/a&gt;)&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Stack trace from the mongod log file,&lt;/p&gt;

&lt;p&gt;Coverity analysis defect 77699: Unchecked return value, problem&lt;br/&gt;
introduced in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-21619&quot; title=&quot;sys-perf: WT crash during core_workloads_WT execution &quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-21619&quot;&gt;&lt;del&gt;SERVER-21619&lt;/del&gt;&lt;/a&gt; change, commit 354c031.&lt;/p&gt;

&lt;p&gt;Instead of calling __wt_evict_page_clean_update() when discarding pages,&lt;br/&gt;
call __wt_ref_out() directly, __wt_evict_page_clean_update() doesn&apos;t do&lt;br/&gt;
any useful additional work.&lt;/p&gt;

&lt;p&gt;This allows __wt_evict_page_clean_update() to be static in evict_page.c,&lt;br/&gt;
rename to __evict_page_clean_update().&lt;br/&gt;

&lt;p&gt;The segfault is because we are trying to evict a page from a tree that has already been closed.&lt;/p&gt;

&lt;p&gt;Following the drop during the start of the next test we see the error. It seems that we need to have the test running inserts and TTL deletes for long enough to get the table big enough, and then drop it to cause the fault.&lt;/p&gt;

&lt;p&gt;Will attach a modified version of the test shortly that should have better luck in reproduction.&lt;/p&gt;</comment>

&lt;p/&gt;

&lt;p&gt;First quick and dirty finding is that the btree&apos;s block manager is currently 0, so thats the cause of the segfault. &lt;/p&gt;

&lt;p&gt;Question now is, why is there no block manager? More to follow.&lt;/p&gt;</comment>

&lt;p&gt;Was there any particular trick to reproducing or were you just running the perf test over and over?&lt;/p&gt;

&lt;p&gt;Can you share your method that finally got a repro going as well as the githash of the binary in question?&lt;/p&gt;

&lt;p&gt;I&apos;d like to do some diving this end and don&apos;t want to spend my time re-inventing the wheel.&lt;/p&gt;

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

I haven&apos;t seen this elsewhere.&lt;/p&gt;

&lt;p&gt;The code at the crash site hasn&apos;t changed recently, but two things occur to me as possibilities:&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;if a collection is dropped, it stays in the system temporarily with pages in cache after the block manager structure is freed.  However, the tree should be marked &quot;dead&quot; in that case so eviction just discards pages from cache without writing.&lt;/li&gt;
	&lt;li&gt;a race during shutdown, where eviction is running as WiredTiger discards trees from cache.&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;Can you please post details about how to run the test?  Even if it doesn&apos;t repro every time, we can leave it running in a loop and see what happens when it fails.&lt;/p&gt;</comment>
