we have CENTOS 4.7 (X86) on DELL server, I already put 32 GB RAM on it. I can use "top" or "free" to check memory and it did show 32 GB. I check REDHAT site and found it say: The "SMP" kernel supports a maximum of 16GB of main memory. Systems with more than 16GB of main memory use the "Hugemem" kernel. I use "uname -r" to check kernel and it show: # uname -r 2.6.9-78.0.13.ELsmp It did NOT show "Hugemem", does this server kernel support 32 GB or not? If NOT how can I change kernel to "hugeme"? Thanks. ______________________________________________________________________________________________________ 付費才容量無上限?Yahoo!奇摩電子信箱2.0免費給你,信件永遠不必刪! http://tw.mg0.mail.yahoo.com/dc/landing
