An update that has one fix can now be installed.


This update for corosync fixes the following issue:

  • Add 'cancel_hold_on_retransmit' config option on corosync totem (bsc#1189680)
  • This option allows Corosync to hold the token by representative when there are too many retransmit messages. This allows the network to process increased load without overloading it. The used mechanism is same as described for the hold directive. Some deployments may prefer to never hold token when there is retransmit messages. If so, the option should be set to yes. The default value is no.
