Ref: question #148866 in Launchpad. I have taken the (admittedly great) liberty of inviting the Kernel team to weigh-in on this since I am beginning to suspect that this may actually be a kernel issue.
Summary: When moving huge files - hundred+gig to terabyte sized file groups - eventually all available RAM and then all available swap is consumed. Running huge file/multi-file copies or moves either from Nautilus (drag- and-drop) or from within a terminal window causes large amounts of memory to be consumed that is not released when the copy is done. Subsequent file copies/moves simply add to the memory consumed. Multiple, simultaneous huge file/group copies simply pour gasoline [petrol] on a raging fire. This has been a problem for me since at least Feb. 22 - 2010 - probably before - and has cost me massive crashes on my file server on multiple occasions. To duplicate this, you will need massive amounts of storage - in the multiple T range - and it will be necessary to create folders full of multi-gig files in the 200G to fractional-T size to move around. (e.g. If I have two 2T drives, one that has abut 1.5+ T of data on it, and the other empty, and I run a "cp -a -v /mnt/huge_drive/* /mnt/huge_drive_2" - and watch the memory allocation either in SysMon, or via top, you will see memory climb steadily (top shows increasing amounts of buffer used). If you are really sadistic, you can repeat the command again once it finishes. My box has 4 gig RAM, and almost 2 gig swap, and doing this a few times rapidly runs all available memory and swap - and then some! - right down the tubes.
