I made this error when I ran into the getpwuid function in both processes of the LXC environment.The current LXC version is 2.0.x and kernel version is 4.4. Has anyone encountered it?
BUG: Bad page map in process ... is a kernel error, and it is very important to keep all the information of the kernel error. The name of the process will help to figure out what is really involved.
Here is a similar report of such a kernel error. The user thought initially that it was a problem with LXC, but later in the discussion they figured out it was a hardware problem, https://old.calculate-linux.org/boards/39/topics/28551
