Hi,
I have found an issue with a Lucene index locking files from a Searcher instance. So that when a mergeSegments happens on a indexwriter close it actually hangs until the search instance is closed This seems to happen only when the index is stored on a network SAN device. When stored elsewhere it acts normally. Lucene version:2.1 and 2.3. going to test later versions. The merge segments hangs here:- DEBUG 12:59:09,993 debug.ThreadDump - at java.io.WinNTFileSystem.delete0(Native Method) DEBUG 12:59:09,993 debug.ThreadDump - at java.io.Win32FileSystem.delete(Win32FileSystem.java:504) DEBUG 12:59:09,993 debug.ThreadDump - at java.io.File.delete(File.java:871) DEBUG 12:59:09,993 debug.ThreadDump - at org.apache.lucene.store.FSDirectory.deleteFile(FSDirectory.java:350) DEBUG 12:59:09,993 debug.ThreadDump - at org.apache.lucene.index.IndexFileDeleter.deleteFile(IndexFileDeleter.java:224) DEBUG 12:59:09,993 debug.ThreadDump - at org.apache.lucene.index.IndexFileDeleter.deleteFiles(IndexFileDeleter.java:217) DEBUG 12:59:09,993 debug.ThreadDump - at org.apache.lucene.index.IndexFileDeleter.deleteFiles(IndexFileDeleter.java:298) DEBUG 12:59:09,993 debug.ThreadDump - at org.apache.lucene.index.IndexFileDeleter.deleteFiles(IndexFileDeleter.java:215) DEBUG 12:59:09,993 debug.ThreadDump - at org.apache.lucene.index.IndexFileDeleter.deleteSegments(IndexFileDeleter.java:177) DEBUG 12:59:09,993 debug.ThreadDump - at org.apache.lucene.index.IndexWriter.mergeSegments(IndexWriter.java:1582) DEBUG 12:59:10,008 debug.ThreadDump - at org.apache.lucene.index.IndexWriter.maybeMergeSegments(IndexWriter.java:1415) DEBUG 12:59:10,008 debug.ThreadDump - at org.apache.lucene.index.IndexWriter.flushRamSegments(IndexWriter.java:1352) DEBUG 12:59:10,008 debug.ThreadDump - at org.apache.lucene.index.IndexWriter.close(IndexWriter.java:588) Once the searcher is closed from a seperate JVM/Server it frees the files and the writer close can finish. Has anyone else seen this behaviour? I see it catches the IO exception on deletefiles in the indexwriter and puts it in delete list for later. But this does not seem to happen on this occasion. it just seems to hang Any ideas on a way round this?
