The /proc/meminfo call is trying to get Linux system memory info for the admin display page. What is the output when you run this command directly in your server? What sort of server is it?

@Andy_Taylor may have some more ideas.

“Stable” doesn’t have the latest code in it for this; I added extra error checking a while back to solve these issues. (see PR#598).

However the Master branch looks like it has been re-written with an alternative solution. (see PR#600).

I’ll get current master branch merged into stable branch. It’s been proven  
to be working well
