+
+      <para>
+        When a <command>mysqld</command> performing replication of a
+        MySQL Cluster that uses <command>ndbmtd</command> is forcibly
+        disconnected (thus causing an <literal>API_FAIL_REQ</literal>
+        signal to be sent), the <literal>SUMA</literal> kernel block
+        iterates through all active subscriptions and disables them. If
+        a given subscription has no more active users, then this
+        subscription is also deactivated in the <literal>DBTUP</literal>
+        kernel block.
+      </para>
+
+      <para>
+        This process had no flow control, and when there were many
+        subscriptions being deactivated (more than 512), this could
+        cause an overflow in the short-time queue defined in the
+        <literal>DbtupProxy</literal> class.
+      </para>
+
+      <para>
+        The fix for this problem includes implementing proper flow
+        control for this deactivation process and increasing the size of
+        the short-time queue in <literal>DbtupProxy</literal>.
