Michael McCandless commented on LUCENE-1342:
--------------------------------------------
Just to confirm, it was at least b28 of 1.6.0_10 (or, now, the released version
of 1.6.0_10) that you see the bug happen?
Paul can you describe how your app uses Lucene? Are you changing any of the
default settings (RAM buffer size, mergeFactor etc)?
A few things to try might be using a single thread for indexing (if you're
using multiple threads now), switching back to SerialMergeScheduler, switching
between autoCommit false vs true, very small or very large ram buffer sizes,
etc. If one of these changes stops the bug or makes it more frequent then it's
at least some progress towards narrowing it down.
