You may be adding an item that is larger than the limit, which is
typically around 4K (may be different for your implementation).

typical.
Dbm creates "gaps" or "holes" in the files it creates. Although the
filesystem reports a large size, the actual number of blocks used is
typically far less. Use 'ls -s' to see the blocksize (given that ls
reports the blocksize correctly).
Also, if you have manual pages for dbm, consult them; they typically explain
these kinds of things.
