IIS 6.0 hangs on 2003 server

Hi,
I have my IIS server hang every day and have to restart to restore verything.
I have taken a dump and the IISState.log
If the experts could shed some light onto the thread stacks, it would be a
great help.

Contents of IISState.log. (I have taken 5 of them with some time interval.
The latest one is attached)
