            <title>[SERVER-77153] Possible division by zero in execution control throughput calculation</title>
                <link>https://jira.mongodb.org/browse/SERVER-77153</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When calculating throughput for throughput probing, &lt;a href=&quot;https://github.com/mongodb/mongo/blob/54ce9f3a48dcde0758e4cdf77d7b0efd08d71e2b/src/mongo/db/storage/execution_control/throughput_probing.cpp#L113-L114&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;we simply divide the number of operations completed by the time elapsed&lt;/a&gt;. While we would expect the time elapsed to never be zero here, we don&apos;t protect against it in case the &lt;tt&gt;Timer&lt;/tt&gt; interface does return zero for one reason or another. Thus we would end up dividing by zero, resulting in a throughput of either Infinity or NaN depending on the dividend.&lt;/p&gt;</description>
