Can you try 1.4.8?

AFS on Solaris only runs on UFS file systems at the moment. I have submitted a
patch to allow it to use any type file system, including ZFS and tmpfs.
See  http://rt.central.org/rt/Ticket/Display.html?id=123677
Also see the Linux tmpfs thread on this mail list. It has similar problems.
