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.
