Sessions lost on the Active device during reboot of the standby

[AtanasBal]

Hi All,

We are experiencing strange behavior in our Fortigate 4401F A-P HA environment. During reboot of the standby device, some sessions, which are carried on the active device, are dropped/stucked.

Does anyone encountered such behavior?

Thank you!

Hi AtanasBal,

I’m Bill from Fortinet, and I’ll be investigating your issue. Could you please provide more detailed information about your device and network?

Specifically, I would appreciate it if you could share the following:

• Current software version
• Session information (diag sys session list)
• Configuration file
• A simple network topology
• Relevant logs (event logs, system logs, etc.)

Please send the information to my email: bhoang@fortinet.com.

Thank you!

Best regards,
Bill
