Good Morning,
We ran into the same thing this week. Two 10.4.7 servers: one an OD Master with the other server bound to the OD master through Directory Access. The second server was our network homes for both Mac and PC student accounts and this was the server that overloaded. Both servers were also bound through Kerberos for single sign-on. The OD Master was set as a PDC and the second server was a “Domain Member”. SMB went nuts on the member server just as yours did. Talked to Apple directly and also talked to an Apple engineer in another district. Here is what we found:
1. The number of automount home folders on our second server was more than three. We needed to consolidate to less than three. We consolidated to one.
2. Since the servers were bound together via Kerberos, we didn’t need the second server to be a “Domain Member” in Server Admin>Windows. Once we demoted it to a standalone server in ServerAdmin>Windows, everything quieted down and the server load was minimal. The number of instances of smbd running on the second server was small and the processor load was great.
We started up three labs of computers (Mac and PC) and had 80+ computers connected to the second server simultaneousy. Left them running for a while. Had no ill effects.
I don’t know if this will help you solve your issue but it is working for us right now. I hope that maybe there is something here that you can use.
Best Regards,
Steve
