I have redhat 7.3 with 4 gigs physical ram on a dual xeon processor.
I'm aware that linux has a 3 gig memory limit for a single process, splitting the 4 gigs into 1 gig of kernel memory and 3 gigs for the user space.
How do I increae my user space memory from 3 gigs to something higher (the closer to 4, the better)? Is there just a parameter I can tune? Will I need to recompile anything?
