Dear rdit, I am not a expert but I had this problem at customer site some days ago. Within a cluster I reboot SA-1; SA-2 was master. As SA-1 was up again the device could not re-join the cluster. The same entries in the log for more then 30 minutes. This caused a continuous automatic failover between the nodes. To solve this I shut down SA-1; SA-2 was master and every think fine. The customer checked their switch and router environment and made some changes. After that SA-1 was started again. Now everythink works fine. Maybe you can check the switch regarding fast port detection or spanning tree. Regards, Felix
