How do I deal with the swap file filling up?
Remove the file /sbin/swapdefaults and reboot.
Digital UNIX has two paging modes, lazy and conservative. Conservative means
that paging space is allocated as memory is allocated, guaranteeing that there
is always somewhere to page to. This limits VM to the size of the paging
partitions, but makes for a very robust system. Lazy is more like what people
are used to with Unix - paging space is allocated when needed for paging out,
you can run more jobs, but you're in big trouble when everything fills up. By
default, Digital UNIX comes up in the conservative mode. Removing the
swapdefaults file changes the system to lazy mode.
