ZyWALL 310 unexpected reboot

Hi!

After updating to v4.39 I had a similar problem with two USG310.

On the first USG310 I had to disable some licensed security features to receive a stable function.

On the second USG310 (no licensed security features) I had to disable ADP to receive a stable function.

@Zyxel_Emily
sent you a PM with some diagfiles.

Thank you.

Hello Zyxel team and community

I don't know if this is the right thread, but we have the same problem with a USG110. Since yesterday the firewall has restarted 4x. We already had this phenomenon about a year ago, but then it only occurred once a week and disappeared after a month.


We have created and saved a diagnostic file.

We are getting our spare ready and will be starting this up tonight. However, when I found this thread, I am not so confident that this will help.

Therefore, I am grateful for any help.

Hi Vic

Thanks for your fast feedback. Please find here my answers:

1. How long had you upgraded the USG110 firmware to 4.62 and how frequently this issue happens?

• We installed the latest firmware v4.62 last night, so for a few hours. Today it has already happened once.
• Yesterday it happened 3x times with version v4.39
• Last year it happened 4x in the interval of about a week. Unfortunately I do not know which firmware we had then.

2. Could you share your running configuration file with us in private message?
Done

3. If this symptom happens periodically, is it possible to connect the console cable and collect the dump to us in private message?
I can make that happen. I just connect to the firewall via RS232. Is there anything else I have to take care of? (Log setting, timeout)

4. Please also send us the diagnostic file with us via private message
Done


Once those information are collected for us, to stablize your network, you can consider to switch the running firmware partition (which running on previous firmware).
Unfortunately, this will not help because the problem ha also occurred with the previous firmware and that is why we made the update.

Hi,

We are experiencing a similar issue with a USG1100.
The reboots started some time after upgrading to 4.39 (may be unrelated) and persist with 4.60 and 4.62.
They seems to occur during higher load periods but the CPU is below 50% .  
"show software-watchdog-timer log" does not contain anything about the crash.

We cannot downgrade as we need SSL Inspection working...
