                    <description>&lt;p&gt;Division or modulo by zero&lt;/p&gt;

&lt;p&gt; The program will have undefined behavior, likely a crash. Division or modulo by zero results in undefined behavior.&lt;br/&gt;
/src/mongo/db/s/shardsvr_get_stats_for_balancing_command.cpp:111: DIVIDE_BY_ZERO 122087 Assigning: &quot;numRecords&quot; = &quot;autoColl-&amp;gt;numRecords(opCtx)&quot;. The value of &quot;numRecords&quot; is now 0.&lt;br/&gt;
/src/mongo/db/s/shardsvr_get_stats_for_balancing_command.cpp:130: DIVIDE_BY_ZERO 122087 In expression &quot;dataSizeBytes / numRecords&quot;, division by expression &quot;numRecords&quot; which may be zero has undefined behavior.&lt;/p&gt;</description>
