Looks like a refcount leak bug has reappeared...
Any chance you could use mc-crusher
(https://github.com/dormando/mc-crusher) and try to set up a config file
that roughly regenerates your traffic? that could help in you finding how
to reproduce it.
In the meantime, I'll give it a good hard stare when I get a chance...
Also; what startup options were you using? Any chance I could see a "stats
settings" and a "stats/stats items/stats slabs" dump from an instance
that's been up a while?
