10.4.7 Craziness with File sharing…

Hello all, i have a new problem that I have been experiencing on a couple different XServe G5's running server 10.4.7 and XSan 1.3. The Xsan mounts volumes that are reshared via AFP. All servers are bound to our AD for users and groups. The server always behaves for a while after reboot, but at some point will start to act strangly. Stage 1: SMB starts making multiple connections per user. As in having 3 connections from "danielc" orignating from the same IP. Soon 10 people logging into the server turns into 100 connections. Soon SMB stops responding to people. Stopping the service doesnt solve the problem. Only a reboot will bring the service back to normal. Stage 2: Once SMB is stopped, the CPU load from the AFP server goes through the roof. I'm talking 145% cpu used. At this point the load starts climbing. Stage 3: Now server admin wont work correctly. Using the serveradmin utility doesn't work. Even serveradmin list will just sit there hanging. A full reboot is the only solution to these problems. What I have done... Following the tuning afp article, I have increaesd the max threads of the afp server to 600. Enabled AFP debugging. I'm hoping its not a corrupt .DS_Store issue as it would get ugly around here quick if I had to delete them all. Any other ideas people may have would be appreciated. Regards, Z
