I am getting this on a 10GB index (via solr 1.3) during an optimize: Jan 2, 2009 6:51:52 PM org.apache.solr.common.SolrException log SEVERE: java.io.IOException: background merge hit exception: _ks4:C2504982 _oaw:C514635 _tll:C827949 _tdx:C18372 _te8:C19929 _tej:C22201 _1agw:C1717926 _1agz:C1 into _1ah2 [optimize] at org.apache.lucene.index.IndexWriter.optimize(IndexWriter.java:2346) at org.apache.lucene.index.IndexWriter.optimize(IndexWriter.java:2280) at org.apache.solr.update.DirectUpdateHandler2.commit(DirectUpdateHandler2.java:355) at org.apache.solr.update.processor.RunUpdateProcessor.processCommit(RunUpdateProcessorFactory.java:77) ...

Does anyone know how this is caused and how I can fix it? It happens with every optimize. Commits were very slow on this index as well (40x as slow as a similar index on another machine) I have plenty of disk space (many 100s of GB) free.
