3.14.1-1-ARCH i686 GNU/Linux:
The applet which is to show the ressources monitoring (cpu load and memory usage) in the lxpanel does only show the cpu load but not memory usage anymore.
The memory usage field in the lxpanel is gone or appears mutilated when right clicking on it. (i686 only)
64bit: 3.14.1-1-ARCH x86_64 GNU/Linux is also affected:
The 'memory usage' field is shown but empty and always tells 'memory usage: 0,0MB (0,00%)'
LTS: 3.10.38-1-lts i686 GNU/Linux is NOT affected.
ARM: 126.96.36.199-2-ARCH armv7l GNU/Linux NOT affected.
Downgrading to kernel 3.14.0-4 (x86_64): issue persists
Downgrading to kernel 3.13.8-1 (x86_64): issue is gone!!
Ergo: It is a kernel 3.14 related issue!
