dpdornseifer opened a new issue #774: CouchDB keeps Crashing
URL: https://github.com/apache/couchdb/issues/774
 
 
   Hi, a CouchDB 2.0 instance keeps crashing right now. We have about 140 different dbs on it. 
   
   ## Current Behavior
   CouchDB shows different errors in the log output. `mochiweb` error occurs all the time in different fashions.
