Subject Re: couchdb.http.ServerError : 500 Bad match, emfile...

Hi!

AFAIK, emfile error is about exhausted file descriptions. Try to tweak
their number for couchdb user in /etc/security/limits.conf .
Another solution could be in increasing ERL_MAX_PORTS environ variable
value (default is 1024), but I'm not sure about this in your case.
