RH4.0 ELhugemem Vs ELsmp
Hi, We have a program which takes around 1.8G memory runtime. We used to run this application on RH2.1 boxes (2.4.9-e.35enterprise) which was restricting total memory (heap + stack) to 2G and often used to go outOfMemory. So, we moved our application to RH3.0 with kernel - 2.4.21-47.0.1.ELhugemem. In this kernel, process memory can go up to 3.4G
Now, we are planning to upgrade to RH4.0. kernel is: 2.6.9-42.0.3.ELsmp
How do I know how much maximum memory this Kernel can use? Is there anything called 'ELhugemem' available for RH4.0?
