No Shards Could be Opened error...

[Dan Santner]

Every few days one of my nodes will fail and start spitting out these errors:

[Wed, 02 Oct 2013 13:38:28 GMT] [error] [<0.16111.356>] [dfc14c40] Uncaught error in HTTP request: {error,

                                                                    {internal_server_error,

                                                                     "No DB shards could be opened."}}

I just restart bigcouch on that node and it disappears......until some unknown future date when it will reappear, repeat cycle.  Seems it's always happening on the same node though, which is curious.

Any ideas?  Sorry I don't know where to find anymore information than that?  Maybe there is a erlang log somewhere I can dig up?

It's not a show stopping thing but it is a bit annoying to have to restart that server once a week.
