Sophos XG 18.5.1.326 is Kernel Panicking

Since updating to 18.5.1.326, I've noticed my firewall is Kernel Panicking at least 5 or 6 times a day. The best uptime I've been able to achieve is 4 hours. I originally suspected hardware, but have since moved the XG to new hardware. Has anyone else seen this issue?

Hello there,

Thank you for contacting the Sophos Community.

Adding to what rfcat mentioned, please check the syslog.log csc.log applog.log and /var/cores.

Regards,

Nothing in the logs i could see that was relevant. I ended up switching back to 18.0 firmware and firewall was stable. Re-applied the 18.5.1 update and so far it's been stable. (18 hours).

Spoke too soon. Just kernel panicked again. 14 hours. Only did it on 18.5. Switched back to 18.0 again to see if its better uptime...

System: Dell Optiplex 780 SFF

CPU: Intel E8400
RAM: 4GB
HDD: SATA SSD 120GB
NIC: Intel PCI Dual Ethernet

Note the system had been completely stable since about April; the issue appears to have only started happenign since the 18.5.1 update. I switched back to 18.0.5 MR-5 build 586 and so far it's been stable again. Also I noticed the certificate error I had where my imported certs weren't being trusted even with the appropriate CA certs being loaded has now resolved itself since switching back.

Still not seeing anything relevant in the logs. I've set up a recorder to capture the screen output next time it panicks. Its only on the screen for 1 or 2 seconds,

Update:

Running for 4 day(s), 3 hour(s), 14 minute(s).

No issues after failing back to 18.0.5 MR-5 Build 586

There must be an issue with the 18.5 build.

Hello there,

Thank you for the update and feedback.

Did you get the change for any core dump under /var/cores? what about the logs?

So far I haven't risked going back to 18.5 yet as its almost certain to crash again. I will try upgrading to 18.5 again tonight and see how it goes.

Currently I am on SFOS 18.0.6 MR-6-Build655 and it's completely stable.

I will report back tonight after upgrading as to how it's going, and if it crashes I will try and capture the core dump.
