Subject Re: CouchDB, linux & clean shutdowns

Hi Robert,

For one view, whenever we loaded it, but every time we loaded it, would produce a stack trace
and not the view. Restarting the CouchDB instance restored the view to working order.

I'll try and dig out the stack trace, but it was the perpetual, continual problem with this
view that led us to take the "nuclear option" and restart.
