wierd error in weblogic due to lucene
Hello,
I am seeing wierd problem with weblogic when I have lot of data in lucene. Wehave a concept of content objects and each content object maps to a lucene document. We tested with 500K objects and lucene even though indexed fine, was creating problems while searching.
When we spawned 25 searches at the same time on weblogic app server, weblogic started un deploying the application. Its wierd, isn't it?
The reason I think lucene is causing this problem is, the root exception given by weblogic is related to number of files open (see below for the exception).
Did anyone see this problem before? Is lucene capable of handling 500K documents?
Why would lucene un deploy the application
<Jul 12, 2004 3:09:56 PM PDT> <Critical> <WebLogicServer> <000204> <Failed to

<Jul 12, 2004 3:09:59 PM PDT> <Notice> <Application Poller> <149404> <Remove

Any help is appreciated.
Thanks
Praveen

Are you sure you close all Lucene IndexReaders/Writers/Searchers? It's best
to close them in a finally block so they get closed even when an exception
is thrown. The number of files shouldn't be the problem. Although you
could of course try with the compound index if your are not using that
already (IndexWriter.setUsecompoundFile()).

Daniel
