Ryan McKinley updated SOLR-173:

    Attachment: SOLR-173-open-files-bug.patch

This is not a real 'fix' but it does make the problem go away.  I don't understand how or why.  Essentially if you use the QueryResponseWriter it runs out of open files - if you write the output directly, it is fine.

It does not seem to make any difference what is in the response.

Anyone have any idea what could be going on?

to make post.sh work with the update handler stuff, you will need to add the content type to <commit/>

curl $URL --data-binary '<commit/>' -H 'Content-type:text/xml; charset=utf-8'

> From brian:
> 1) Download trunk/nightly
> 2) Change line 347 of example/solr/conf/solrconfig.xml to   <requestHandler name="/update" class="solr.XmlUpdateRequestHandler">
> 3) java -jar start.jar...
> 3) Run post.sh a bunch of times on the same xml file... (in a shell script or whatever)
> 4) After a few seconds/minutes jetty will crash with "too many open files"

> # lsof | grep solr | wc -l
