It appears to be a bug in the OS X Server serial number verification framework, when multiple network interfaces are in use. I experienced this issue on 10.5.8 Server, with XSAN 2.2.
I updated OS X Server with the 10.5.8 Server Combo Update v.1.1, which resolved the issue in my case. You can download the update here:

And resolved in the 10.6.1 Server update:
