During regular activity and index delta build we got the following error: ERROR - 2015-03-30 04:06:12.318; java.lang.RuntimeException: [was class java.net.SocketException] Connection reset at com.ctc.wstx.util.ExceptionUtil.throwRuntimeException(ExceptionUtil.java:18) at com.ctc.wstx.sr.StreamScanner.throwLazyError(StreamScanner.java:731) After additional 2 minutes we got the following error: ERROR - 2015-03-30 04:07:39.875; Unable to get file names for indexCommit generation: 638 java.io.FileNotFoundException: _tu.fdt at org.apache.lucene.store.FSDirectory.fileLength(FSDirectory.java:261) at org.apache.lucene.store.NRTCachingDirectory.fileLength(NRTCachingDirectory.java:178) And since than Solr wasn't recover until we did full rebuild of all documents. Detailed log attached. Let me know if you familiar with such issue. And what can create such issue that prevent from recovery and requires rebuild index. This is major issue for us.
