Leopard server AFP no longer allows connects

Hi, I am looking for a solution or work around for the following problem. It is also discussed in the following discussion. http://discussions.apple.com/thread.jspa?threadID=1224346&tstart=0 I see this happening on my server with PHD's . When resting the server they work fine for while, syncing goes o. then hours later sudden the login fails. It seems from what I read that the the kerberos ticket is not renewed. The logs give this info: FileSyncAgent.log [2007/11/24 09:58:21.010] Starting automatic sync of "HomeSync_Mirror". [2007/11/24 09:58:21.019] -[SPeer_FS_PHD mountPeerVolume]: Unable to write to root of PHD remote home ("/Network/Servers/server.files.lan/Users/jfk").
