Mark,
Which exact version of the JRE are you using?

Actually that stack trace looks like it's from trunk, not from 2.3.2
(pre)? OK, I think you said it's from "post 2.3 trunk".
Right...the Lucene that showed the problem was build from a trunk grab
late last week. One of the problem indexes was built with a 2.0 or 2.1
and the other was built with a post 2.3 trunk (but weeks (prob months)
before the one i grabbed late last week :) )
Another question: is autoCommit false or true?
false
If I can get you an affected index I will.

Hi Mark,
Not good!
Can you describe how this index was created? Did you use multiple
threads on one IndexWriter? Multiple sessions of IndexWriter
appending to the index? addIndexes*? Is the index copied from one
place to another after being written and before being searched?
Both sites were created by a single thread on a single IndexWriter.
Updates are done through multiple threads and one IndexWriter. No
addIndexes. Index was never copied, always same path.
If you run CheckIndex, what does it report?
This was my next move...unfortunately, someone accidentally kicked
off a
complete reindex before I could do it. From what I can tell by the
stack
trace, its a per doc problem...I am guessing I could have
printed the
ids of the problem docs and just reindex those? I have to deal with
this
at many other sites, so that may be my attack...I cannot reindex
everything to fix.
It would be great to know if that workaround works (and indeed it's a
per-doc issue). I'd also love to know how many docs are affected,
when you hit this.
If there's any way to zip up the index and send it to me, even just
the files for the one segment that has the corrupted doc, that'd be
great.
Any prior exceptions on this index?
Not that I can recall. One of the indexes was made months ago, prob
with
a 2.0 or 2.1 Lucene, the second was made with a post 2.2 Lucene. One
site was windows 2003, the other AIX. One site was only 30,000
docs, the
other over 1 million.
Are your docs a variable schema (different fields)?
Yes. Lots of different fields depending on the doc.
Mike
Thanks Mike. I am currently trying to duplicate this. I can't go to
another site without testing some kind of fix.

Any recent changes that would expose index corruption?
I am getting two new errors when trying to search:
nullpointer fieldsreaders line 260
indexoutofbounds on fieldinfo line 185
I am kind of screwed, because reindexing fixes this, but I cant
reindex!
Any ideas?
