Blocking New Connections in ClusterXL LS while under load
Symptoms
  • /var/log/messages file on cluster member shows one of the following messages:

    • State synchronization is in risk. Please examine your synchronization network to avoid further problems !
    • State synchronization of this machine is in risk. Please examine your synchronization network to avoid further problems !
    • State synchronization on member <ID> is in risk. Please examine your synchronization network to avoid further problems !
Cause

Refer to ClusterXL Administration Guide (Chapter 'Monitoring and Troubleshooting Gateway Clusters' - ClusterXL Error Messages - Sync Related Error Messages).

This message can appear when the machine is under extremely high load, when a Delta Sync update was permanently lost.

A Delta Sync update is considered to be permanently lost when it cannot be retransmitted because it is no longer in the transmit queue of the update originator.
This scenario does not mean that ClusterXL will malfunction, but rather that there is a potential problem.
