We're having a 2.0R production system that is becoming unusable due to 
a nasty bug: whenever you do a pwd_mkdb, the root filesystem leaks
around 1 megabyte of memory (the password file is around 1000 entries,
the *db files are 650K each). The pwd_mkdb processm finishes normally.
There are no files left, except that df shows the drop:

[/etc] root@iaehv> df . ; pwd_mkdb -p aaaa ; df .
Filesystem  1K-blocks     Used    Avail Capacity  Mounted on
/dev/sd0a       49383    18014    28899    38%    /

I have absoloutely no idea of whats going on here. But you can imagine
the system becoming rather unusable :-(

I verifed things on freefall, and current doesnt have this bug anymore.
So it has been solved, sometime ago. 
As you can understand, I'd like to have some fix for 2.0R. Is
there anyone who knows what is causing this?
