An AppleShare system error occurred
We replaced our file server from PowePC to Intel Xserver and we get this Error, the workaround is to stop start the Xsan volume.
My suspicion is that when MDC failover occurs to intel Xserver something gets screwed but I cant test this since this is a production environment...
I opened bug report 5021854 at Apple bug reporter I will post there any info that comes up from users here.
