man vnconfig
man vn

Those will let you configure a regular file as additional swap. A
better solution for a production machine would be to repartition your
drive to have a larger swap partition.

You may have to compile a new kernel with pseudo-device vn.

Suggested command:

vnconfig -c -T -S 75m /dev/special_file_to_use /path/to/regular/file

Then you would use swapon /dev/special_file_to_use to add the 75 megs
of swap to your existing 85, yielding 160.
