 The default value is yes.
 
+.TP
+cancel_token_hold_on_retransmit
+Allows Corosync to hold token by representative when there is too much
+retransmit messages. This allows network to process increased load without
+overloading it. Used mechanism is same as described for
+.B hold
+directive.
+
+Some deployments may prefer to never hold token when there is
+retransmit messages. If so, option should be set to yes.
+
+The default value is no.
