this values is approx (7.61 GB) but my Physical Memory size is only 6144 Megabytes.

Can this happen ?
If your NGZ physical memory is capped, this can indeed happen. kernel memory is shared by all zones so is not restricted by capping.
What says, from the global zone:
Code:
echo ::memstat | mdb -k

?

Physical disk IO size smaller than fragment block filesystem size ?

Hello, in one default UFS filesystem we have 8K block size (bsize) and 1K fragmentsize (fsize). At this scenary I thought all "FileSytem IO" will be 8K (or greater) but never smaller than the fragment size (1K). If a UFS fragment/blocksize is allwasy several ADJACENTS sectors on disk (in a ...
