Re: [Thinstation-general] Ram limit at 895MB

[Don C. <don...@ya...>]

./build --kernel SMP
 
This will build with the SMP that has highmem and PAE. This will let ts see up to 64gb of memory.

We are using TS as workstations without a HD, they all boot over the 
network.
We use a few different type of machines, but they all have 2GB RAM, yet 
TS only reads 895MB or so.
This is causing us to be running out of memory, crashing the application.

ts_80ee7333263e:/$ free -m
              total         used         free       shared buffers
Mem:           883          378          504            0 45
-/+ buffers:                333          550
Swap:            0            0            0

I see in the logs:

Is this a built in restriction in the TS kernel, or is there a way for 
me to enable HIGHMEM?

Thanks!
