HA - Heartbeat interfaces goes up and down

[kal]

Hi,

I have a Fortigate 100D Cluster HA.

Since 3 hours, the heartbeat interfaces goes up and down, causing log entries like

1 - "Heartbeat device(interface) down"

2 - "Virtual cluster detected member dead"

3 -  "Virtual cluster detected member dead"

4- "HA device(interface) peerinfo" 

5- "Virtual cluster detected member join"

6- "Virtual cluster member state moved" 

Can you please help me to understand what' s happening ? What's more, during the incident, I have no Internet.

Best regards.

[size="2"][size="2"][size="2"][size="2"][size="2"][size="2"]it look  like the HA   heartbeat  interface flap, it will make HA cluster member can not see each other. You may increase (CLI:config sys ha/set hb-interval  x/set  hb-lost-threshold) to increase the tolerance.[/size][/size][/size][/size][/size][/size]
