HA1 Backup link went down root cause analysis

HI Team,

 

I have issue in Palo alto firewall 3260 where HA1 backup link went down. Eventhough there is no production impact i'm seeing this issue happened without any cable change or any activity.

 

This is due to ping failure for heart beat , But I want to know what caused this ping failure issue.

 

I have already running PANOS 8.1.4-h2 which says release notes that HA1 Backup port issue unexpected behaviour was fixed.

 

Below is error message

 

Error Msg
---------
flags    : 0x2 (close:)

Regards

Venky
