Hi Everyone, Recently we have migrated from lucene 2.2 to lucene 2.9.3.
We are having some issues in search. During the load, searchers are getting hung up. When we took a process stack, we sound that there are around 450 threads are in the blocked state. Thread t...@885: (state = BLOCKED) - org.apache.lucene.store.SimpleFSDirectory$SimpleFSIndexInput.readInternal(byte[], int, int) @bci=7, line=115 (Compiled frame) - org.apache.lucene.store.BufferedIndexInput.readBytes(byte[], int, int, boolean) @bci=203, line=136 (Compiled frame) - org.apache.lucene.index.CompoundFileReader$CSIndexInput.readInternal(byte[], int, int) @bci=51, line=247 (Compiled frame) - org.apache.lucene.store.BufferedIndexInput.refill() @bci=87, line=157 (Compiled frame) - org.apache.lucene.store.BufferedIndexInput.readByte() @bci=12, line=38 (Compiled frame) - org.apache.lucene.store.IndexInput.readVInt() @bci=1, line=78 (Compiled frame) - org.apache.lucene.index.TermBuffer.read(org.apache.lucene.store.IndexInput, org.apache.lucene.index.FieldInfos) @bci=6, line=64 (Compiled frame) - org.apache.lucene.index.SegmentTermEnum.next() @bci=64, line=129 (Compiled frame) - org.apache.lucene.index.SegmentTermEnum.scanTo(org.apache.lucene.index.Term) @bci=25, line=160 (Compiled frame) - org.apache.lucene.index.TermInfosReader.get(org.apache.lucene.index.Term, boolean) @bci=211, line=232 (Compiled frame) - org.apache.lucene.index.TermInfosReader.get(org.apache.lucene.index.Term) @bci=3, line=179 (Compiled frame) - org.apache.lucene.index.SegmentReader.docFreq(org.apache.lucene.index.Term) @bci=12, line=997 (Compiled frame) - org.apache.lucene.index.DirectoryReader.docFreq(org.apache.lucene.index.Term) @bci=25, line=633 (Compiled frame) - org.apache.lucene.index.FilterIndexReader.docFreq(org.apache.lucene.index.Term) @bci=9, line=195 (Compiled frame) - org.apache.lucene.search.IndexSearcher.docFreq(org.apache.lucene.index.Term) @bci=5, line=147 (Compiled frame) - org.apache.lucene.search.Similarity.idfExplain(org.apache.lucene.index.Term, org.apache.lucene.search.Searcher) @bci=29, line=765 (Compiled frame) - org.apache.lucene.search.TermQuery$TermWeight.<init>(org.apache.lucene.search.TermQuery, org.apache.lucene.search.Searcher) @bci=28, line=46 (Compiled frame) - org.apache.lucene.search.TermQuery.createWeight(org.apache.lucene.search.Searcher) @bci=6, line=146 (Compiled frame) - org.apache.lucene.search.BooleanQuery$BooleanWeight.<init>(org.apache.lucene.search.BooleanQuery, org.apache.lucene.search.Searcher) @bci=72, line=184 (Compiled f rame) - org.apache.lucene.search.BooleanQuery.createWeight(org.apache.lucene.search.Searcher) @bci=6, line=415 (Interpreted frame) - org.apache.lucene.search.BooleanQuery$BooleanWeight.<init>(org.apache.lucene.search.BooleanQuery, org.apache.lucene.search.Searcher) @bci=72, line=184 (Compiled f rame) - org.apache.lucene.search.BooleanQuery.createWeight(org.apache.lucene.search.Searcher) @bci=6, line=415 (Interpreted frame) - org.apache.lucene.search.Query.weight(org.apache.lucene.search.Searcher) @bci=8, line=99 (Interpreted frame) - org.apache.lucene.search.Searcher.createWeight(org.apache.lucene.search.Query) @bci=2, line=230 (Interpreted frame) - org.apache.lucene.search.Searcher.search(org.apache.lucene.search.Query, org.apache.lucene.search.HitCollector) @bci=3, line=110 (Interpreted frame) - lucene.searcher.MySearcherThread.run() @bci=99, line=52 (Compiled frame) I have a feeling that these blocked threads are the causing searcher not to respond. Our application is running on SunOS and we are using jdk1.6_04 Thanks in advance.. Vipin
