This sounds exactly like the problems we had with 2GB RAM machines.
Could it be that this people where malloc crashes or sunrpc due
building the glibc use kernels with 2GB RAM support enabled ?
(sunrpc crashes on malloc in the cases I know).

There was a bug in the kernel where the kernel rounds an address
wrong or so.

Linux is like a Vorlon.  It is incredibly powerful, gives terse,
cryptic answers and has a lot of things going on in the background.
