[Dxspider-support] Spider crashed overnight, can’t see why

Wed Jun 11 19:37:58 BST 2025

Keith, I had the same question. Looks like the only way to really control Livepatch is through configuring the update check time interval or using an on-prem Livepatch distribution set-up. In either case the scheduled reboots are not controllable (https://tuxcare.com/blog/the-security-gap-why-canonicals-livepatch-falls-short-of-true-protection/#:~:text=The%20practical%20implication%20is%20clear,Trapped%20in%20a%20Patched%20State).

Command to change update check interval...

sudo canonical-livepatch config check-interval=360

Keith,

Have you considered running DXS in a Docker container?  Not immune to kernel-level changes but does provides better isolation. 9M2PJU has an excellent tutorial on this if interested.

73,

OK, it’s good to have an explanation.

I don’t mind it doing it during the week but not at weekends.  Is there a way to stop this from happening on Saturdays and Sundays?

Just checked WT3Q and it restarted as well, so others probably in the same boat.

Cononical has updated many core services over the weekend i.e. systemd. My test node after updating restarted DXS. This was probably the case for you.

Thanks Chris.

Here we go, having looked in syslog, I suspect this is due to having Ubuntu Pro with Livepatch enabled.  I know there were about 25 patches available on the server yesterday and today it’s down to 15 so some must have installed overnight.   It’s been running like this for nearly two months and updates have been installed before without restarting the spider service.

73 Keith.

Messages is similar to /var/log/syslog. If you have that you may want to look there as well.

Morning all,

I noticed this morning that my node only had a couple of hours uptime.  Looking in the debug log, it restarted at 05:24z.

Debug log attached, it doesn’t format very well if I paste it in.

I can’t see any reason for the crash here - Can anyone?  Dirk?

Thanks,

73 Keith.
