MiguelSR opened a new issue #1033: Application start failure when running single node
URL: https://github.com/apache/couchdb/issues/1033
 
 
   Hello!
   
   I installed a 3-nodes cluster of CouchDB in 3 AWS instances. I got a problem with memory so I tried to change some settings of the instances (to be precise, add more RAM). But then I couldn't start my instances again. Now I'm back to the normal configuration and I can't run a single instance because I got the following errors in my log
   
   ```

   ```
   
   The first message is seen once for each database.
   
   I'm running it via Docker, exposing my own /opt/couchdb/data and /opt/couchdb/etc. There are like 4 or 5 databases created (that before this problem worked perfectly).
   
   The problem seems to be about some file that can't be read, because of some permissions or lock issue, but I have no idea.
   
   Just to add some information, I created the cluster manually, not via Fauxton.
   
   I hope that someone can help me :).
   
   Thank you very much.
