This are Dual > Quad Core servers (CPU Intel) with 16GB RAM using a 32Bit kernel. This is a common problem with running 32-bit kernels with more than 8Gb RAM. (Search the archives and you will find similar problem reports.) Anyone in your situation has two options - Preferred one is to switch to a 64-bit kernel. In most cases you can just upgrade the kernel to 64-bits and use the same 32-bit userspace. It works fine. If you cannot for some reason upgrade to a 64-bit kernel, the second option is to try and use RHEL/CentOS kernels which according to Alan Cox are better tuned for this kind of setup and you have a better chance that they will work.
