I think that is a bit overreacting. ndoutils is a database client. 
Databases need management and tuning to get you good performance - 
that's just routine, regardless of the brand you are using: mysql, SQL 
Server, Oracle, Postgres, .... No amount of work or "polishing" will 
change that. There's a reason DBAs are highly valued professionals.

For that matter, my database would have had this problem regardless of 
ndoutils. It's just that ndoutils writes a lot more to the database than 
my other applications (by nature, not ndoutils' fault).

By the way, the tuning I suggested seems to have done the trick. It's 
been running for more than a week without a hitch, and without the 
increase in disk space I had observed before.
