            <title>[SERVER-26239] Improve handling of WT_CACHE_FULL for inMemory storage engine</title>
                <link>https://jira.mongodb.org/browse/SERVER-26239</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;There are multiple places in the code where there are problems related to handling &lt;tt&gt;WT_CACHE_FULL&lt;/tt&gt; error returns.  Three examples of code paths that need to be changed to handle &lt;tt&gt;WT_CACHE_FULL&lt;/tt&gt; properly are:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;If an index build would use more space than is available in memory.  The particular error is encountered while cleaning up after such a problem, the solution is to retry the cleanup until it succeeds.&lt;/li&gt;
	&lt;li&gt;In &lt;tt&gt;WiredTigerSessionCache::releaseSession&lt;/tt&gt; the call to &lt;tt&gt;haveDropsQueued&lt;/tt&gt; results in a call to &lt;tt&gt;syncSizeInfo&lt;/tt&gt;, which results in an update to the size storer table that can fail.&lt;/li&gt;
	&lt;li&gt;When an index build fails due to cache full, the path to rolling back the index build involves first updating the MongoDB metadata table via &lt;tt&gt;KVCollectionCatalogEntry::removeIndex&lt;/tt&gt;. Since the cache is full, doing the update into the metadata also fails with &lt;tt&gt;WT_CACHE_FULL&lt;/tt&gt;.&lt;/li&gt;
&lt;/ul&gt;
