SubjectRe: Linux 2.3.31 bug using large memory
Nagy,

i believe this to be normal behaviour.

applications that use brk()/sbrk() can only allocate up to ~730mb.
for a single application to use more memory, it needs to allocate memory
using something like mmap().

take a look at how dlmalloc works - and see what happens.


cheers,

lincoln.
