Domino Sametime server freezes

[Database Administrator]

Hi all!

We have a Domino server release 7.0.2 which acts as a Sametime server and
archiving server. We have this problem tah when starting Domino the server
runs ok for a couple of minutes and then the whole machine gets
unresponsive. It's looks normal but har frozen totally and only option is to
do a hard-reboot. checked log file and found this row that constantly shows
up in log:

WARNING: Domain "domain name" is your remote primary domain, and no replicas
are available. Your server cannot process users and groups. Please contact
your system administrator



Any ideas what this is nad can it cause server to freeze like this?



Thanx!
