Situation
While trying to read a beast from disk, the ZFSMAL_ReadBlk funciton
got a read failure and was trying to report an error to the
system. The buffer structure for the IO in progress contained
a pointer to the actual 4K cache buffer address where the data was
supposed to be put, but the 4K address caused a Page Fault,
implying that the address was not mapped. The
ZLSS_ErrorRecord function was simply trying to read the first
longword of this buffer and pagefaulted. A 4K page that NSS
believed belonged to it's cache was simply unmapped by the
kernel.
Resolution
This is resolved in SERVER.EXE dated April 11, 2006 or later. It
can be found in NW65OS5a.exe.
