Hmm, do we speak about kernel zone? I have made a test case:

#!/bin/bash                                                                                                                                                   
set -x

PAGE_SIZE=$(/usr/bin/pagesize)

ZFS_MEMORY_PAGES=$($KSTAT2 -p kstat:/vm/usage/memory:mem_zfs | cut -f 2)                                                                                      
AVAILABLE_MEMORY_PAGES=$(( $FREE_MEMORY_PAGES + $ZFS_MEMORY_PAGES ))                                                                                          
AVAILABLE_MEMORY_PERCENTAGE=$(( 100*$AVAILABLE_MEMORY_PAGES/$TOTAL_MEMORY_PAGES ))

In my zone I have

$ prtconf | head -2
System Configuration:  Oracle Corporation  i86pc
Memory size: 4094 Megabytes

$ bash a.sh
+ KSTAT2=/usr/bin/kstat2
++ /usr/bin/pagesize
+ PAGE_SIZE=4096
++ /usr/bin/kstat2 -p kstat:/vm/usage/memory:mem_total
++ cut -f 2
+ TOTAL_MEMORY_PAGES=1047965
++ /usr/bin/kstat2 -p kstat:/pages/unix/system_pages:freemem
++ cut -f 2
+ FREE_MEMORY_PAGES=555988
++ /usr/bin/kstat2 -p kstat:/vm/usage/memory:mem_zfs
++ cut -f 2
+ ZFS_MEMORY_PAGES=162092
+ AVAILABLE_MEMORY_PAGES=718080
+ AVAILABLE_MEMORY_PERCENTAGE=68

That looks ok to me. Would you mind running that snipped and/or be more specific about the errors, please?
