Greetings everyone!

 

A while ago I posted about my server becoming unresponsive and at the time I was unable to capture diagnostics logs. Today it became unresponsive and I was able to capture logs via SSH. Reviewing the syslog, it seems a page fault of some sort happened shortly before I was unable to access things. The weird part was the WebGUI was inaccessible except for the Main tab (some of it would load but not the full page towards the bottom). Also, all dockers were running just fine.

 

I did attempt to remove the primary network connection after the inaccessibility happened to determine if there was a fault with the primary. This did not resolve the issue. Any insight as to what the fault might mean? No changes have been made to the system except updating dockers.

 

Here is the issue I have identified from the syslog:

Any insight would be appreciated. Thank you :)

 

Per the recommendation of the 'Need Help? Read Me First' post, I will be upgrading to unRAID v6.10.1 to see if that might fix it but was curious as to the page fault meaning for this specific issue.

Macvlan call traces are usually the result of having dockers with a custom IP address, upgrading to v6.10 and switching to ipvlan might fix it (Settings -> Docker Settings -> Docker custom network type -> ipvlan (advanced view must be enable, top right)), or see below for more info.

Thanks @JorgeB I will take a look at doing that the first chance I get :)
