Hello noc_92,


We are still looking for someone to help you.

We will come back to you ASAP.

Just need to ask a few questions to understand better. How are you determining this is the FortiGate causing traffic to stop routing?


Are you sure it's the FortiGate and not something else? I.e. maybe it's your WAN link? When the issue happens can you still route between two internal interfaces on the FortiGate?

I'm getting the same issue.

We have two Fortigates 1801F in HA. 

In the past, the 2 incident only occurred in the same unit. But now, it has ocurred on the other unit.


When a unit is the Primary HA, without doing any changes, the communications drops and we have to change to the other node as Primary to recover the service. The only option is reboot the Primary unit to change the HA.

In January was reproduced with the 7.0.9 version. Now, we upgraded to v7.0.10, and with the new version, the incident has returned.

I don't see any error logs.

It seems that the unit doesn't accept new connections, and only works the old connections. For exemple, If I'm connected via GUI when the incident occurs, I can navigate through the GUI, but I can't do ping or connect via SSH.

This incident not occurs always.

that issue we inform to Fortiget support team they check all logs and debug reports..they say it was an OS bug issue. and they give solution updates to the latest version. and update the os to 7.2.4, but that issue was not fixed that issue came sometimes,

the Fortiget support team checks again and they give us a script to schedule.

they say need to restart the WAD process.



config system auto-script
edit "restart_wad"
set interval 43200
set repeat 356
set start auto
set script "diag test app wad 99"


after that issue does not appear again...
