[Mono-list] Large memory usage on a 64bit machine

[Anset]

Hi,

I'd assume that a 64bit kernel is propperly configured, but you might 
take a look at the kernel settings for the cpu.

On 32bit cpus, by default the kernel only maps 880MB.

To be able to use all the RAM on a 1GB machine or better, the kernel 
needs to be recompiled.

Go into 'make menuconfig' (or whichever config is preferred) and set the 
following option:

Processor Type and Features ---->
High Memory Support ---->
(X) 4GB

Hope this helps,

Anset
