[Commotion-admin] [commotion-openwrt] Nodes are crashing, out of memory (#40)

[Ben West]

I am running zram-swap as described above on WasabiNet nodes, both 5.8GHz mesh backhaul and 2.4GHz mesh APs, and I can confirm that certain processes do not like to be swapped out, freezing or behaving erratically as a result.  hostapd, wpa_supplicant, olsrd, crond/busybox, and whatever your captive portal agent is (nodogsplash or coovachilli), all certainly shouldn't be swapped out.  Possibly commotiond too, although I've not had opportunity to test that.

So, the zram_swap method described above lacks a bit in robustness.  I think the mlock command can be used to prevent specific processes from being swapped out, although I'm uncertain of whether OpenWRT has this tool integrated.
