That is still really small for 5MB documents. I think the default solr document cache is 512 items, so you would need at least 3 GB of memory if you didn't change that and the cache filled up.
Try disabling the document cache by removing the <documentCache class="solr.LRUCache" size="512" initialSize="512" autowarmCount="0"/> block from your solrconfig, or at least turn it down to like 5 documents. -Kal -----Original Message----- From: jim.bl...@pbwiki.com [mailto:jim.bl...@pbwiki.com] On Behalf Of Jim Blomo Sent: Thursday, June 03, 2010 2:29 PM To: solr-user@lucene.apache.org Subject: Re: general debugging techniques?

Are there other memory flags I should specify? Jim
