How to find cause of strange reboots?

Brad Shannon

Hi folks, appreciate your help in advance.

 

I have an XG85 running SFOS 17.0.2 MR-2.

It is set up to send logs to a Syslog server I set up just yesterday. [https://i.imgur.com/BoNeNsB.png] [https://i.imgur.com/0h1MnvD.png]

That server is receiving some logs. [https://imgur.com/TRA2qDl]

 

Twice in the last 48 hours, the device has rebooted itself during times of high usage. What log settings should I configure to see what could be causing this, in case it happens again?

 

(Also, maybe it's related to SFOS 17?)

 

2/27/18 UPDATE:

  • updated to 17.0.5, same reboot problem.
  • replaced the hardware, restored settings to replacement, same reboot problem.
  • tried factory reset and manually re-entering the settings, same reboot problem.

I have a replacement non-Sophos FW en route. However, I got some interesting data from the COM port just now, which I'll add as a new reply below.

    The firewall just rebooted again. I don't know why. I don't know how to find out why.

     

    This is a work-critical device malfunctioning with no evidence of any problem on the network, no evidence of any issues that would affect hardware (eg, power outage), and extremely minimal use of the firewall's advertised capabilities.

     

    I'm now going to open a support ticket with Sophos and attempt to replace this device with a firewall that does not exhibit unpredictable behavior.

    Hi Brad,

    In my experience, the reason for restarts is too small RAM memory in XG85 (2GB). Restarts occur when the XG85 performs an automatic update of the IPS patterns and needs more RAM. What to do ? (1) Turn off automatic pattern updates and do it manually or (2) Turn off unused processes and functions, eventually turn off ATP and IPS.
