            <title>[SERVER-62748] spill_to_disk.js fails burn-in tests with &quot;WT_CACHE_FULL: operation would overflow cache&quot; error</title>
                <link>https://jira.mongodb.org/browse/SERVER-62748</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The test creates up to 200MB of test data and that seems to stress the WT cache when the test is run in repeat mode on Enterprise RHEL 8.0 (inMemory) for the burn-in check.&lt;/p&gt;

Also, this seems to be an issue only on the burn in tests task, but not when run once regularly in a suite.&lt;/p&gt;</comment>
                            <comment id="4300518" author="kyle.suarez" created="Wed, 19 Jan 2022 16:20:00 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=mihai.andrei&quot; class=&quot;user-hover&quot; rel=&quot;mihai.andrei&quot;&gt;mihai.andrei&lt;/a&gt;, taking a look at the linked patch build, it looks like cleaning every 20 executions still isn&apos;t enough. &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=irina.yatsenko&quot; class=&quot;user-hover&quot; rel=&quot;irina.yatsenko&quot;&gt;irina.yatsenko&lt;/a&gt; has suggested reducing the amount of memory used by the test, to avoid stressing memory-constrained systems like the inMemory storage engine builder. Perhaps we could dial down the size of the documents, as well as &lt;tt&gt;internalQuerySlotBasedExecutionHashAggApproxMemoryUseInBytesBeforeSpill&lt;/tt&gt;, to maybe half of the current size? Even more?&lt;/p&gt;</comment>
