            <title>[SERVER-19066] Out Of Memory issues with WiredTiger during index build</title>
                <link>https://jira.mongodb.org/browse/SERVER-19066</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Our Deployment Environment:&lt;br/&gt;
=======================&lt;br/&gt;
Shared Replica Set.&lt;br/&gt;
Ubuntu Machine.&lt;br/&gt;
Everything was running fine until WiredTiger Upgrade. We have 4 shards per Linux Instance. Upgraded from MMAP to WiredTiger i.e. Deleted all the data and let it sync with Primary and during sync we are getting Out Of Memory Error and the mongod process running for that shard exits.&lt;br/&gt;
We have a 15GB Memory Instance so we assumed 3 GB reserved memory for other system processes and for each mongod instance running per shard we set cacheSizeGB to 3 GB.&lt;/p&gt;

&lt;p&gt;Error Stack Trace:&lt;br/&gt;
================&lt;/p&gt;

The mongod process is using more than configured cacheSizeGB but doesn&apos;t seem to exceed 1.5x times the configured values thereby preventing out of memory error.&lt;/p&gt;</comment>
