            <title>[SERVER-22231] Add additional test suites to run resmoke.py validation hook</title>
                <link>https://jira.mongodb.org/browse/SERVER-22231</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-22121&quot; title=&quot;Add resmoke.py validation testing hook to test suites&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-22121&quot;&gt;&lt;del&gt;SERVER-22121&lt;/del&gt;&lt;/a&gt; has only 2 YAML files, which have the validation hook enabled:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;core.yml&lt;/li&gt;
	&lt;li&gt;sharding_jscore_passthrough.yml&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;We should investigate adding the following suites:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;concurrency&lt;/li&gt;
	&lt;li&gt;&lt;del&gt;concurrency_replication&lt;/del&gt;&lt;/li&gt;
	&lt;li&gt;&lt;del&gt;concurrency_sharded&lt;/del&gt;&lt;/li&gt;
	&lt;li&gt;jstestfuzz&lt;/li&gt;
	&lt;li&gt;jstestfuzz_replication&lt;/li&gt;
	&lt;li&gt;jstestfuzz_sharded&lt;/li&gt;
&lt;/ul&gt;

It makes sense these two suites that were failing; they were the only ones that ran more than one mongod on the same VM (2 mongods in a master-slave configuration in this case).&lt;/p&gt;</comment>

                            <comment id="1195867" author="igor" created="Tue, 8 Mar 2016 00:32:02 +0000"  >&lt;p&gt;Thanks for the investigation Robert!&lt;/p&gt;

&lt;p&gt;I&apos;m running the tests on machine and even if they&apos;re not failing, I see that calling validate() fills up the block cache pretty quickly. With validate() my block cache grows to 5GB pretty quickly; without it, it stays around 1GB.&lt;/p&gt;

&lt;p&gt;By default we set block cache to be 1/3 of the total RAM available: &lt;a href=&quot;https://github.com/mongodb-partners/mongo-rocks/blob/master/src/rocks_engine.cpp#L206&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb-partners/mongo-rocks/blob/master/src/rocks_engine.cpp#L206&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;What might be happening here is that mongod process using 1/3 of machine RAM is too much. How much memory do those machines have? Let me try defaulting RocksDB memory size to a smaller amount, with calculation similar to what Wiredtiger does: &lt;a href=&quot;https://github.com/mongodb/mongo/blob/master/src/mongo/db/storage/wiredtiger/wiredtiger_init.cpp#L72&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/blob/master/src/mongo/db/storage/wiredtiger/wiredtiger_init.cpp#L72&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Alternative, we could pass in --rocksdbCacheSizeGB=1 (&lt;a href=&quot;https://github.com/mongodb-partners/mongo-rocks/blob/master/src/rocks_global_options.cpp#L46&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb-partners/mongo-rocks/blob/master/src/rocks_global_options.cpp#L46&lt;/a&gt;)&lt;/p&gt;</comment>

&lt;p&gt;I did some investigation and it looks like the OOM issue is caused by the &lt;tt&gt;validate&lt;/tt&gt; command running after every test. I used &lt;tt&gt;malloc_history -highWaterMark&lt;/tt&gt; to check the memory usage on OS X and here is the stacktrace.&lt;/p&gt;

&lt;p&gt;&lt;tt&gt;mongo::RocksRecordStore::validate&lt;/tt&gt; calls into rocksdb &lt;a href=&quot;https://github.com/mongodb-partners/mongo-rocks/blob/master/src/rocks_record_store.cpp#L703&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here in rocks_record_store.cpp&lt;/a&gt;;&lt;/p&gt;

&lt;p&gt;There doesn&apos;t seem to be a glaring bug in the validation code, which is very similar to WiredTiger&apos;s, the issue may simply be that rocks uses more memory when doing a collection scan. But if I remember your talk correctly, rocks should be excepted to use more memory than a b-tree based implementation when doing reads?&lt;/p&gt;

&lt;p&gt;If you think there&apos;s room for improvement in the rock&apos;s memory usage, I&apos;d be happy to play around with it after a fix. At the same time, I&apos;ll try to ask our AWS team for a larger instance for the rocksdb builds. If you have other suggestions for fixing this build failure, please feel free to let me know as well.&lt;/p&gt;

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

&lt;p&gt;FYI I wasn&apos;t able to reproduce the failure on my machine, but that was probably expected as it has a lot of memory and this is an OOM issue. I should probably try reproducing on smaller memory machine.&lt;/p&gt;</comment>
