This has just become an important issue - the same thing now seems to be happening on the model town NAS box, though I'm sure it didn't before. I reverted both our setup scripts and the river system software to old versions to no avail (including not running the river system software at all). "free" should report physical "real" memory usage right? If I'm mistaken there it could explain the numbers. The NAS box had only 14M or 256M free earlier despite showing no process using that much memory. It usually only uses about 50M if memory serves. Unfortunately the NAS box only has very basic (mostly busybox) utilities that seem to be extremely unhelpful when diagnosing this because they all report virtual memory size. Any ideas at all? I'm clutching at straw a bit here. Hamish
