You do (e): remove the cron job that goes through and purges files from
/stratch. I'm away from my NetBSD box right now, but if I remember correctly,
/scratch is one of the directories searched for old files to delete. When
your files get over the age limit, the cleanout script deletes them. After
doing (e), (c) is still a valid option.... ;)
Often, something that happens with some regularity can be traced back to
a cron job that someone is running.
Hope this helps,
