[SunHELP] swap lost?

[Sangbutsarakum, Patai]

Dear gurus
I'm so surprise when I've found this thing 
I'm running Solaris 2.6

# df -k
Filesystem            kbytes    used   avail capacity  Mounted on
/dev/dsk/c0t0d0s0    4573659 1419136 3108787    32%    /
/proc                      0       0       0     0%    /proc
fd                         0       0       0     0%    /dev/fd
swap                 3487320      16 3487304     1%    /tmp

# swap -l
swapfile             dev  swaplo blocks   free
/dev/dsk/c0t0d0s1   32,121     16 4194272 4165792

# top
...
Memory: 2048M real, 1113M free, 14M swap in use, 2034M swap free

I think 3 number that shows number of swap space is not the same.
I've no any idea about it.

Please suggest
Thanks in advances
