Veit, What OS / compiler were you testing this with? I'm not sure, but this could be due to the same threading issue we already aware of. Were you able to run the atomic tests from the test suite successfully?
As you know, a move to using boost::threads is in our agenda. Done right, this could resolve a lot of other threading issues as well. In the meantime, try perhaps applying the threading related fixes Ben has pushed recently to his branch (ben_working), and let me know how it goes. HTH, Itamar. -----Original Message----- From: Veit Jahns [mailto:nuncupa...@googlemail.com] Sent: Friday, March 19, 2010 1:01 PM To: clucene-developers@lists.sourceforge.net Subject: [CLucene-dev] Multithreaded write and search Dear all, in our application we have several threads writing and searching on the index. Writing and searching isn't a problem as long the IndexSearcher isn't updated,i.e. deleting the old and creating a new IndexSearcher. But if the IndexSearcher is updated, then the application crashes. Not every time, but with high probability. The problem is also occurs also, if every search thread has it's own IndexSearcher. Then an update isn't needed. But the applications crashes too, because---I suppose---the IndexSearcher is deleted at the end of the thread. I think it's a bug. But I don't exclude that I made an error in reasoning. So any hint is much appreciated. I wrote a test case and putted it in the file TestThreading.cpp The complete file is attached to this e-mail.
