The whole 8G physical memory is available in our system, the point we concerned is that the kernel cannot use more than 2G memory in kernel space. AFAIK there is still only 4G virtual memory available for one process in i386 even if the PAE is enabled, and the upper part of the 4G virtual memory is mapped to the kernel memory. For example, if the KVM size is 2G, then there is only 2G left for one process because the upper 2G is mapped to kernel space. So there is still a limitation of KVM size in i386 with PAE. The limitation should be 2~3G I think. Since the server is on line now, we cannot re-install it to i386 to check this. We'll try it if we have spare machines.
