Ok, I'm actually not sure I need to run this. But it is strange that it failed.
This is my situation. I would like to have the lucene index kept
updated because:
(1) I'm still using ArtifactBrowse aspect:
<aspect name="Artifact Browser"
path="resource://aspects/ArtifactBrowser/" />
(2) I'm using SRW and it has an interface with lucene rather than discovery.
So what I think I need to do to have lucene index kept current ( just
for searching ) is to run
(1) have this in dspace.cfg
event.dispatcher.default.consumers = search, versioning, discovery,
eperson, harvester
(2) When I release the dspace 4.1 code run this:
./dspace index-lucene-init
AND
(3) run this as a cron job nightly:
./dspace filter-media
Does this make sense?
My only problem now is that when filter-media goes to update the
indecies, I get a whole bunch of these errors:
2014-06-27 12:42:36,344 ERROR org.dspace.search.DSIndexer @
java.io.FileNotFoundException:
/dspace/repository/dev/search/_68y0_Lucene41_0.tip (Too many open
files)
Any guidance with this will be greatly appreciated.

(1) ./dspace index-lucene-init
