Hi List,

Since we migrated from dovecot 1.2.4 to 2.2.12 with lucene as FTS engine, I have this in my error log:

Apr 22 14:01:14 indexer-worker(username): Error: lucene index /var/vmail/username/lucene-indexes: IndexWriter() failed (#1): Lock obtain timed out Apr 22 14:01:14 indexer-worker: Error: indexer-worker [username@mydomain.com MailBox-1 - 20800/22707]: /home/anotherusername/newnew/clucene/src/core/CLucene/index/DocumentsWriter.cpp:210: std::string lucene::index::DocumentsWriter::closeDocStore(): Assertion `numDocsInStore*8 == directory->fileLength( (docStoreSegment + "." + IndexFileNames::FIELDS_INDEX_EXTENSION).c_str() )' failed. Apr 22 14:01:14 indexer: Error: Indexer worker disconnected, discarding 1 requests for username@mydomain.com Apr 22 14:01:14 indexer-worker(username@mydomain.com): Fatal: master: service(indexer-worker): child 31158 killed with signal 6 (core not dumped) Apr 22 14:01:16 imap(username): Error: indexer failed to index mailbox MailBox-2

Does that sound familiar to someone ?

Thanks.
