It's not necessary to send your message several times to multiple
mailing lists.

Could you provide some additional details, such as what release of
Kerberos you're running, what OS, how you have configured the KDC
database, etc.?  What is the rate at which the KDC is serving
requests?  Do you have heavy kadmin traffic?  How often do you get the
lock error?
