Too many view files may be held open, rendering CouchDB unusable
----------------------------------------------------------------
Key: COUCHDB-180
URL: https://issues.apache.org/jira/browse/COUCHDB-180
Project: CouchDB
Issue Type: Bug
Components: JavaScript View Server
Affects Versions: 0.9
Environment: OS X 10.5.5
Reporter: Paul Carey
Attachments: test_for_open_files.js
On trunk (rev 728285), CouchDB will hold onto view files for a certain request
pattern.
Once a threshold of open files has been exceeded, all requests to CouchDB will
result in {error,emfile}.
The attached test case runs through the following sequence n times.
delete db
create db
create doc
query non existant view
create view
query view
On my machine a value of about 250 for n is enough for the threshold to be
exceeded. Regardless, running lsof clearly shows CouchDB holding multiple refs
to the same view file.
