strange kdc lockup

[Leif Johansson <leifj@it.su.se>]

We have been seeing frequent kdc lockups on our slave kdcs during the
last few weeks. We are of course running the latest heimdal and krb4
versions and using hprop to replicate every hour. 

Every now and then (typically once or twice a week) the slave kdc:s
stop accepting requests. A restart fixes the problem. The log is silent.
Has anyone seen anything like this?

The slaves are running psoriasis 7 and the master is freebsd. The 
master never locks up. The slaves serve v4, v5 and ka-tickets and
are also tramsarc afs db servers.

	Cheers Leif
