Andrew,
	Thanks for your mail.  I've not seen those errors before.  I will  
definitely dig and see what I can come up with.  How much memory is in  
this system, and how much of it is used when this starts to occur?   
Does it happen all the time?  Do you have kernel lock override turned  
on, or what is the kernel set for in preemption?  If you could give me  
some more details, I would be glad to see if I could help out.  Thanks
