>                 Key: LUCENE-1193
>                 URL: https://issues.apache.org/jira/browse/LUCENE-1193
>             Project: Lucene - Java
>          Issue Type: Bug
>          Components: Search
>    Affects Versions: 2.3
>         Environment: LINUX, JRUN4, APACHE, 3GB RAM
>            Reporter: vaidy
>
> Lucene Index contains 2.1 Million records (indexed from 2.1 million records from sqlserver
DB). 
> Lucene Index file Size 256MB
> Lucene version: 2.3
> Searching works fine when we sort the results on a single field. However, if the search
results is sorted on more than one field we get Out of Memory exception. 
> We restrict the number of search results to 250
> Out of Memory exception is quite consistent in 2.3.  We recently moved from 2.0 to 2.3.
 
> Version 2.0 also used to give the OOM but not this frequent.
