Old, old joke: Patient: Doctor! It hurts when I do this! Doctor: Don't do that. This is a well known issue with malloc backed md disks. Use swap backed ones. They will be the default in V7. They have all of the advantages of malloc backed mds without the possibility of eating all available memory and crashing the system. malloc backed md disks are very dangerous and should only be used in special circumstances and with great care. -- R.
