SunOS hermes 4.1.3_U1 4 sun4m,

>Description:
We are getting multiple kernel panics after upgrading to 1.2b6.  This is the third
panic we received in the last two days.  Folowing is the dump from the messages
file.
Notice the line: "pid 10160, `httpd': Data access exception"

I am going back to 1.1 to and will see if the panics stop.

but nothing at 09:25.
