Shane commented on LUCENE-2327:
-------------------------------
I believe at the time we were storing on a NAS via NFS. If my memory serves me
well, there were known issues with running Lucene over NFS at the time. We
were experiencing issues with the file system at the time so have since moved
to a different architecture.
Also, I was aware that the fix drops the segments, but thanks anyway. :)

> Reporter: Shane

> When retrieving the scoreDocs from a multisearcher, the following exception
> is thrown:
> java.lang.IndexOutOfBoundsException: Index: 52, Size: 4
> at java.util.ArrayList.rangeCheck(ArrayList.java:571)

> The error is caused when the fieldNumber passed to FieldInfos.fieldInfo() is
> greater than the size of array list containing the FieldInfo values. I am
> not sure what the field number represents or why it would be larger than the
> array list's size. The quick fix would be to validate the bounds but there
> may be a bigger underlying problem. The issue does appear to be directly
> related to LUCENE-939. I've only been able to duplicate this in my
> production environment and so can't give a good test case.
