Hi Michael,

I have a few Alix 2D13 PBX running in the field (with Asterisk 11 though). They usually have between 100 and 50 MB of free RAM.
I always create my own builds for them and leave out all packages that I don't need (e.g. netsnmp, Zabbix).

I also don't enable Monit on Geode CPUs, cause there are some memory related issues over a longer time period.

I you want I can send you my Buildroot .config file offlist. 
Since there will be no official Alix/net5501 builds in the future, you need to build yourself anyway.

Michael
