Check the man page (and the source). It looks as if "export MALLOC_OPTIONS=Z" will cause malloc to touch every page and zero it out. This may be in part what you are wanting. Also, you can compile in malloc_options = "Z" to acheive the same affect without having to always export the environment variable. Of course, when you do this, your process will (might) still be killed immediately or at some point in the future, which I think is what you are trying to avoid :( -Brian -- Brian Dean brd...@unx.sas.com To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-current" in the body of the message
