FS#479 - Softethervpn results in ReAlloc error after vpnbridge is executed
User who did this - Ron Brash (ronniebrash)

I will investigate the execution, but you are correct - the memory consumption is what is causing this issue.  I have removed portions of the applications such that I only need the vpncmd and vpnbridge applications; the device doesn't crash.

I also had to play with the sysctrl var for min_free_kbyres (lowered it to 2048, and have been experimenting with 1024) and this also is increasing system stability.

I may have to work with the gentlemen who provided the package softether to LEDE/Openwrt to help make it more modular to reduce the run-time size.  He was only testing on MIPs.
