------------------------------------
No we are notusing IndexReader.setNorm. Just opening the reader. Reading
indexes and closing it.
the limit of the OS is set to large number already about 80000 or so

> Hi,
> Has anyone seen the NullPointerException as shown below
> before? We have used Lucene to build a public site search functionality.
> All the IndexReader objects in there are closed appropriately except one that
> throws the following error and results in (too many files open) exception.
> This brings the entire site down.
> The lucene version we are using is lucene-core-2.9.2.jar
>
> Any idea what could cause this exception?
