Q: PBX GUI system status shows yellow or red under "App Memory". This appears to indicate I am out of memory. Is this going to cause problems.
A: PBX GUI system status app memory indicator currently shows app memory + cached/buffered memory. Technically, cached memory should be subtracted from used memory to get a more accurate indication of memory usage. So most of the time this indication is not a problem.
To get a clearer picture of actual memory usage issue the following from a Linux command line in a console window.
free -mo
You should see something like the following:
[root@host ~]# free -mo
total used free shared buffers cached
Mem: 256 249 6 0 0 85
Swap: 0 0 0
Subtract used from cached to get 249-85=164MB actual application memory used out of 256MB total.
So FreePBX system status is indicating the 249/256=97% used memory when actual usage is 164/256=64%.
UPDATE: As of PBX GUI v2.10, system status now reports memory - cached so this should not be a problem anymore.
