So I updated my containers today. Ubuntu 16.04 base OS and container OS. Two of my containers, both “coincidentally” running an updated Apache2 instance, but both on completely different physical machines (with their LXD instance, own zpool etc.) gave an error as shown in the attached image. Now it might not be an issue with LXC, but just in case, I thought I’d post something here as a heads-up.
I can’t see anything other side effects yet, although “coincidentally”, my systems now seem very sluggish (but that could be my remote internet…).
Anyone have any idea as to why these errors would be triggered?
