I noticed that the AWL database was getting rather large, so I used the

removed a lot of entries from the database, it did not reduce the database size.
Does anyone know what kind of a database this is, and in particular, how to do
a cleanup that will remove unused records? The database is currently located
on a RAM drive, so space is important due to scarcity as well as the potential
speed issues from letting it grow too large.
I noticed a similar issue (user mail quotas getting eaten by large AWL
files) back around 2.5x, and hacked the check_whitelist script to shrink
the AWL file.

Check that it's set up with the right hash type (DB_File for any 3.x SA
version) - I'm not sure whether the posted version is derived from the
one I hacked up on Debian woody or not. <g>
Note that you'll need free space wherever the file is up to the size of
the current file.
There is no way I know of to shrink BerkelyDB files in-place. >:(
