Sorry for dropping off the face of the earth, but glad you found a
root cause.  But... that's also a strange issue to have, since the
password DB access should be pretty damn fast, even with a local DB.

Going from 600 down to 1 entry (but I assume you left all the other
system passwd entries?) shouldn't make a difference, unless there's
just no caching what so ever of the passwd DB.

Are you using a dedicated proftpd only password file?
