Martins Balodis commented on COUCHDB-1652:
------------------------------------------

I tried different versions of couchdb and erlang. All of them had the same problem.
Ubuntu 14.04, CouchDB 1.5.0, erlang R16B03
Ubuntu 14.04, CouchDB 1.6.1, erlang R16B03
Ubuntu 14.10, CouchDB 1.6.1, erlang 17

> 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.
> I see this on all installations on Ubuntu 8.04, 10.04 and 12.04 all 64bit with CouchDB
1.2.0 and 1.2.1 with Erlang 14b4.

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