After updating from 2.14pro to 2.18pro I get a "500 Internal Server Error" error when trying to access when accessing the server status page. Thanks for your help :-)

I found the issue: /proc/meminfo doesn't contain MemAvailable at /opt/admin/src/AppBundle/Server/System.php:47

MemAvailable is indeed not in /proc/meminfo. As a workaround I replaced

'available' => _parseVal('MemAvailable', $contents) with 'available' => _parseVal('MemFree', $contents).

Maybe the issue is also with my docker version as I updated that before updating to poste 2.18 pro

SH repo owner
This code was add with ~~#444~~

What host distribution are you using?

SH repo owner
I see, MemAvailable seems to be present only on newer kernels

Alexander
My Kernel is 3.10.102
- 2018-10-30T09:01:54+00:00
SH repo owner
- changed status to resolved
fix ~~#484~~ hide memory chart on older kernels without MemAvailable

I think you need kernels 3.14 or above for this
