Mike, just to bring closure on this one. It is definitely not Lucene problem, as after restart the same index on disk was loaded into RAMDirectory and is in production since Friday, no problems around. This index serves 350k / Queries per day in average.
It is still not clear to us how this could have happened, this is read only index, fully optimized, gets only searched. And in spite of it, we have seen this funny corruption... it escapes me... this index was 67 days used on this same machine without problems, but java/OS/memory chips managed to corrupt it in memory. I have recommended burn-in tests for this machine, with spec focus on memory... ----- Original Message ---- > From: Michael McCandless <[EMAIL PROTECTED]> > To: java-dev@lucene.apache.org > Sent: Friday, 18 April, 2008 4:56:14 PM > Subject: Re: Strange Exception > > > Some sort of index corruption seems likely.
