USG FLEX 500 FIREWALL FREEZES AND REBOOTS

PaoloArlotti

I'm having issues with two USG FLEX 500s in HA (High Availability). Every 2 to 4 days, they freeze (PWR+SYS LEDs off and port LEDs blinking)."

The tests I have performed are:

• Shut down the passive firewall and leave only the master active.
• Shut down the master firewall and leave only the passive one, promoted to master

The problem still occurs.

Mode: onpremise Firmware: 5.39(ABUJ.1) 

After enabling debug mode, I collected these logs:

Has this issue been occurring since the first day the HA setup was deployed, or was it running normally for a while and only started happening recently? Or do you have any configuration changed recently?

To look into freeze/reboot issue, I would like to know more about your network environment. Please check your inbox, I will leave a message to you, thanks.
