Is it supposed to go on into infiniti?

I couldn't figure out how to break out of it, and the above is nowhere near all 
the output ... it just seemed to keep looping through the same values on the 
left column ... from a script session:

io# grep 0xffffff004c7dc720 /vm/neptune
  101637 (0xffffff004c7dc720)  sched_switch() at sched_switch+0x11f
  101637 (0xffffff004c7dc720)  sched_switch() at sched_switch+0x11f
io# grep 0xffffff007ba18be0 /vm/neptune
  101201 (0xffffff007ba18be0)  sched_switch() at sched_switch+0x11f
  101201 (0xffffff007ba18be0)  sched_switch() at sched_switch+0x11f

I couldn't break out after I typed 'show threads' ...

The server had hung, I broke into DDB ...

I'll be surprised if the above means anything to anyone, but, unfortunately, by 
that point all I coudl do was power cycle :(
