How many unique fields do all of the xml files contain (even approx)?

[ https://issues.apache.org/jira/browse/SOLR-857?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Ruben Jimenez updated SOLR-857: ------------------------------- Attachment: solr.zip I did some poking around and think I pinpointed the source of the memory problems. I took Bill's advice to look for a large HashMap so I walked through each of them in the heapdump and found that there were 16 rather large HashMaps. Each of these had a size of over 120,000. Upon further inspection I also found that these 16 Maps seem to be three distinct Maps. I came to this conclusion by looking at the first item found in each to group them initially and then confirmed this by choosing two additional random locations per group to verify the each map location contained the same object. See FieldInfoSample.PNG to see a sample. This may not be related but I did a Google Search for lucene fieldinfos leak 2008 and the following came up: http://mail-archives.apache.org/mod_mbox/lucene-java-commits/200809.mbox/[EMAIL PROTECTED] Assuming I'm unable to find a way to reproduce this error without a rather large number of these files should I just start zipping them and uploading one at a time?Memory Leak during the indexing of large xml files -------------------------------------------------- Key: SOLR-857 URL: https://issues.apache.org/jira/browse/SOLR-857 Project: Solr Issue Type: Bug Affects Versions: 1.3 Environment: Verified on Ubuntu 8.0.4 (1.7GB RAM, 2.4GHz dual core) and Windows XP (2GB RAM, 2GHz pentium) both with a Java5 SDK Reporter: Ruben Jimenez Attachments: OQ_SOLR_00001.xml.zip, schema.xml, solr.zip, solr256MBHeap.jpg While indexing a set of SOLR xml files that contain 5000 document adds within them and are about 30MB each, SOLR 1.3 seems to continually use more and more memory until the heap is exhausted, while the same files are indexed without issue with SOLR 1.2. Steps used to reproduce. 1 - Download SOLR 1.3 2 - Modify example schema.xml to match fields required 3 - start example server with following command java -Xms512m -Xmx1024m -XX:MaxPermSize=128m -jar start.jar 4 - Index files as follow java -Xmx128m -jar .../examples/exampledocs/post.jar *.xml Directory with xml files contains about 100 xml files each of about 30MB each. While indexing after about the 25th file SOLR 1.3 runs out of memory, while SOLR 1.2 is able to index the entire set of files without any problems.
