Its not just ubuntu..Maybe I'm wrong but I've had occasions where all programs were using a lot more memory that they should have been and the system gets sluggish and its been down (or rather fixed by) fixing menu.lst to run the latest install kernel so I'm assuming that if you are running a glibc and kernel that dont 'match' then perhaps malloc is misbehaving allocating memory, not getting a message in time to say the memory has been made available, and asking again? When I've had it is seems process are using close to integer multiples of what they should be .
