`NIS database is bad'?

[Per Foreby]

SunOS 4.1, Sun3

We are having problems with the NIS passwd database. We have about 1600
entries, one master server and 6 slave server.  The problem: The database
becomes corrupted. "ypcat passwd" stops after a few entries with the error
"NIS database is bad".  This seems to happen when people change their
yppasswords so I suspect that it has to do with the yppasswdd.  Could
anyone help me?  (email - I'll summarize)
