----------------------------------------

             Summary: CouchDB does not release disk space from .deleted files
                 Key: COUCHDB-1652
                 URL: https://issues.apache.org/jira/browse/COUCHDB-1652
             Project: CouchDB
          Issue Type: Bug
          Components: Database Core
            Reporter: Simon Eisenmann


I noticed on long running servers a disk space increase over time. Though the database in
itself did not grow. After investigation i found that there are lots of files still open which
have already been deleted.

lsof |grep deleted

CouchDB should release the file pointer on those files, to release the disk space to tools
like df.
