why the cluster is going crazy

bggazownianetbggazownianet
in Firebox - FireCluster

We are use HA active/passive cluster. (2x M270)
Each member of the cluster works properly about 2-3 hours and later failover occurs.
After next 2 - 3 hours - again failover occurs.
Machine's are under protected power (UPS) and temperature is ok about 18 st Celsius

Cause of failover: heartbeat lost
What to do? Recreate the cluster?
I do not believe that both machines were damaged in the same way
I have already changed the cluster cables

I attached:

Cluster status: (power is ok, there is no reason to restart, no man will restart machines for many days,)

    If the M270 devices is connected directly to each other, i would suspect a hardware failure on one of the devices, maybe a NIC issue.

    Have you checked the NIC status on each device?

    Do you have other equitment running in the same lan with the same vrrp address?

    If the boxes are loosing heartbeat it's likely due to a process crash or the devices rebooting for some reason. I'd suggest opening a case so that our team can dig into the boxes a bit more in depth and see what might be causing that problem.
