Hi there,
I've recently migrated from Windows Homeserver (Windows Server 2003 based, 32-bit OS) to Windows Server Aurora ( basically Vail, aka Homeserver 2, but with Active Directory, Windows Server 2008 R2 based, 64-bit OS).
Since there's no add-in as yet for Vail, I've installed SBS "standard". First I tried 7.5 but for some reason it didn't want to scan my music folder, so I switched to 7.6 (info below), dutifully upgrading each time it tells me there's a new version available. I also have Trackstat and Spicefly Sugarcube enabled.

Version: 7.6.0 - r31499 @ Mon Nov 8 02:08:56 PST 2010
Hostname: BK-AURORA
Server IP Address:
Server HTTP Port Number: 9000
Operating system: Windows 2008 Server R2 - EN - cp1252
Platform Architecture: 586
Perl Version: 5.10.0 - MSWin32-x86-multi-thread
Database Version: DBD::SQLite 1.30_06 (sqlite 3.7.2)

Now for my question: since the migration I experience random stops of the players. When it happens I see that the SBS process on the server is taking around 50% of CPU. Only solution I've found so far is either ignore the situation and wait a while (quite long sometimes) or restart the service. Does anybody have a clue what could be the cause of this behaviour?
