Sophos XG firmware 18.0 MR4 Internal Server Error

Hi Nilesh R Lad :  This issue with V18 MR4 is getting observed if "Refreshing the packet capture page with wrap buffer on"  over GUI packet capture. This is known to Sophos team with ID NC-64984 and as of now this issue fixed version taken in V18 MR-5. 

Without restarting appliance, TOMCAT service ( GUI service) restart will fix the issue.

TOMCAT service restart command:

For Single device ( or Non HA setup): 

#service tomcat:restart -ds nosync

If device in HA

#service tomcat:restart -ds sync

I ran the command "service tomcat:restart -ds nosync" but it didn't work. the shell shows "503 service failed" error.

Hi Kafu Hacin,

Request to share the output of tomcat.log

Login to SSH > 4. Device Console > 5. Device Management

# tail -f /log/tomcat.log

In another SSH session, run the command to restart tomcat service.

# service tomcat:restart -ds nosync

It wont let me SSH into it. 

Could you please take console access to the firewall? You can either use a standard console cable or a micro USB cable.

Yes i am able to take console access but when i entered password on console it gives the following error. 

There seems to be an issue with the hard disk. I'd suggest opening a support case with a Disk Test output. Ensure to share the serial number and license number in the case description. Also please share case ID via PM.
