| Subject: | Corrupted Indexes Under Lucene 2.3 (and 2.3.1) | Actions... |

After upgrading to Lucene 2.3 (and subsequently 2.3.1), our application has experienced sporadic index corruptions on our larger (and more frequently updated) indexes. These indexes experienced no corruptions under any prior version of Lucene (which we have been using for several years).
The pattern of failure seems to be consistent. First, we receive an exception like the following:
java.lang.IndexOutOfBoundsException: Index: 4788, Size: 4762
at java.util.ArrayList.RangeCheck(ArrayList.java:547)
at java.util.ArrayList.get(ArrayList.java:322)

at java.lang.Thread.run(Thread.java:619)
When we experience this error, we run a writer.flush() then a writer.close().
Then, we get this exception when trying to re-open the index:
org.apache.lucene.index.CorruptIndexException: doc counts differ for

Running the check index application included with 2.3 enables us to remove the bad documents from the index, but this workaround is less than desirable. It would be greatly appreciated if anyone could shed some light on our issue.
