In order to test Kerberos V4 with a large database, I attempted to add 20000
principals (to a database that had only a couple of dozen entries). But
my expect script (that talks to kadmin) just stopped (with no messages in
any Kerberos log files) after adding principal number 11510. When I looked
at the 'virtual' size of principal.pag (with ls), I saw about 1.5 gigs!
If I understand it correctly, ndbm doubles the virtual size of the
database whenever two keys have the same hash. Your expect script is
probably producing many principal names with the same hash value. Try a
different algorithm for naming your 20000 principals (e.g. pseudo-random
strings).
