XG310 random reboot many time.

Question

Hi, 
 My product: XG310 (SFOS 17.5.13 MR-13) 
 I've just updated from 17.5.8 MR-8 to MR-13. It's working fine after a few days, it's auto-reboot without any advance notice. I didn't figure out what happened to my firewall. Has anyone faced this issue? 
 It's often auto reboot in business hours, especially during peak hours and so annoying when it caused the company to completely lost the internet. 
 Need help from Sophos. 
 Thanks.

Hi Hung Ho 
 Thank you for reaching out to the Community! 
 Could you please check if firewall-acceleration is enabled on your firewall? if it is enabled, please disable it and monitor the issue. 
 To disable the firewall-acceleration, SSH into the XG firewall and from the main menu run the following command: system firewall-acceleration disable 
 Replace " disable" with " show" to check the status. 
 Note: If disabling Firewall Acceleration, does temporarily resolve the problem, this still needs to be investigated. 
 I'd also suggest you set up a console connection to capture the next restart event if it ever happens. 
 Thanks,

Hi Hung Ho 
 You would not even notice any changes in terms of the performance once you disable the firewall-acceleration. 
 Let me know if how it turns out for you once you disable it. I would also suggest you set up a console logging. 
 Follow the KBA to set up a console connection: Sophos XG Firewall: How to setup a Serial connection with a console cable . 
 
 Using PuTTY, go to 'Session' - 'Logging' 
 Select "All session output', and set the file name to a folder and name for later retrieval. 
 Configure the Serial connection to use the proper COM port on your PC, and a Speed of 38400. 
 Start the session, and log in to ensure it is all proper. 
 Once logged in, you can leave it there, or log out and leave the session at the password prompt. Either way, leave the session active and allow it to capture the output from the next reboot. 
 Once that reboot takes place, you can end the Serial connection, and provide the PuTTY log file via PM. 
 
 Note: Be sure that the computer in question does not go into Standby or Hibernate while logging.
