Strange df output on solaris 9

Hi all,
After deleting some large log files on solaris 9 machine I can see strange df output shows below

/dev/vx/dsk/rootvol     45G 16384E    50G 39879076698694% /

I thought it will back to normal once I restart it but did not. I have seen in sunsolve article 6362734 that "Solaris 8 and Solaris 9 are not impacted by this issue". Could anyone help to solve this issue.. I looked into the forums but did not find any solution.. Here is the uname -a output.
SunOS myhost 5.9 Generic_117171-02 sun4u sparc SUNW,Sun-Fire-280R.
