+ <message>
+
+ <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>.
