Ok - that'd be with or without MMAP enabled? (note that so-far, without 
MMAP I'm not seeing any errors - throughput is running about half what I 
was seeing with MMAP enabled (before crashing that is). CPU is also way 
busier (also to be expected). One other observation - I had been seeing 
lots of DNS errors - IPV6 related format errors I really didn't think 
much of it as they were mostly .ru and seemed spam-related, but now I 
don't see any. Haven't updated bind; doubt the world has changed - so 
perhaps this is related to the network issue.
